Title: List of Game Genie codes
Post by: JC on September 20, 2007, 03:20:56 AM
Post any Genie codes you discover or aren't in the code book (post the game, the code and what it does). I'd love to have a page or whatever on the site with cool codes.

but wouldn't this only benifit the like 2 of us who have Famicom Game Genies?

Or are we including NES codes as well?

Batman (NES):

PEOPPZ/PEOPPG/PEPPPG - Vertical Wall Jump (any of them)

Let's you do this:

Double Dragon 3 (NES):

NYVVLZAE,NNVLOGPE - 255 Continues
AEKNPPIA - Have Jimmy Enabled

Super Mario Bros:

EPOISS - Destroy blocks

-not quite as good as the SMB3 code, but worth a try

does anyone know any Game Genie codes for Rockman 2? I want to play some various insanely difficult rom hacks, but I can't seem to find any codes anywhere. Mega Man 2 codes don't work.


Title: Re: List of Game Genie codes
Post by: MaxXimus on December 27, 2007, 02:54:46 PM
I was fooling around with Rockman2 hex and I stumbled upon a code that makes your suit yellow and lets you kind of glide through the air(as a pose to using an attack). If you are on the ground and you use the attack it just makes your arms and legs rapidly change between the jump stance and the standing stance. This code is actually very helpful. If I can find where I wrote it down, I'll post it.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on December 27, 2007, 10:41:59 PM
Sounds cool. The only code I really am interested in in infinite energy if you happen to have that  ;)


Title: Re: List of Game Genie codes
Post by: UglyJoe on December 28, 2007, 08:17:47 PM
Rockman 2 infinite energy: SXOVTSSE  (this is the same as the SXXTPSSE code for Megaman 2).

By the way, WHAT IS GOING ON WITH THIS CODE?!

I'm afraid it'll break my NES! ;D


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on December 28, 2007, 10:38:19 PM
Sorry to triple post, but hey UlgyJoe, do you happen to have other codes for Rockman 2? Of course the inf. health is the most handy one, but I'd like to see if there are other codes as well, such as inf. lives and those crazy super jumps. 


Title: Re: List of Game Genie codes
Post by: UglyJoe on December 28, 2007, 10:40:23 PM
I can convert pretty much any Megaman code into a Rockman code.  The infinite lives code should work for both.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 19, 2008, 03:39:52 AM
Can we get this thread stickied? I feel it something that should be kept up with.


Does anyone have any codes for Earthnound Zero/Mother? I'm looking for codes that will work with the traslated ROM.

infinite cash or quick EXP gain would be nice.

Does anyone have any codes for Earthnound Zero/Mother? I'm looking for codes that will work with the traslated ROM.

infinite cash or quick EXP gain would be nice.

Quick EXP gain: OZSUZGOU, GASULGAT (you need both codes).  That'll give you 1024 exp plus a little bit for any enemy that you kill.

Lotsa Gold gain: OZNLAGOU, NYNLPGAV (you need both codes).  That'll give you 65025 gold plus a little bit for any enemy that you kill.  I don't know what happens if you max out your gold, so be careful.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 20, 2008, 10:23:25 PM
sweet! Thanks a lot uglyjoe.

just out of ceriosity, how are you able to generate codes? I can't seem to find any codes relating to Mother at all.


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 20, 2008, 10:31:36 PM
I use an emulator with a debugger and the knowledge of how Game Genie codes work.

(ps, lotsa gold codes added)


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 20, 2008, 11:51:08 PM
Sweet. Thanks so much uglyjoe. How difficult is the process? If it isn't too bad, I have a few other games I'd like codes for at your leasure:

all of these are the Famicom (J) versions in case you need to know.

Akumajou Special - infinite health? I'd like to finish it. Some of the later stages are quite difficult.


Chuuka Taisen, Dragon Spirit, Parodius da and Gradius II - infinite lives, and possibly the ability to retain powerups after death. I know there's codes similer to these with the NES Gradius and Lifeforce if they at all help.

Getsufuu Maden - infinite health.

Konami Wai Wai World 1 - infinite heath. This game can kick your ass if you dont pay attention and its because of its difficulty that I dont like it nearly as much as its sequal.

Sword Master - just infinite health. wow this game's hard.

(Namco) Star Wars - infinite health. you die soooooooooooooo easily I've never made it past the water world.

no rush with any of these, they are just on my list to beat and are stubborn due to unfair difficulty.


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 21, 2008, 12:42:22 AM
Sweet. Thanks so much uglyjoe. How difficult is the process?

It varies from game to game, but it's generally not too hard.

Akumajou Special - infinite health? I'd like to finish it. Some of the later stages are quite difficult.

That's the Dracula-kun game, right?

I didn't test these too much, but they appear to work:

infinite life:
XVESEIVK, XVESOSXX

when you die, gain a life instead of losing a life:
VVXSVGVG

I'll work on the other ones sometime.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 21, 2008, 03:42:44 AM
wow thanks uglyjoe! your quick!

I just thought of something else that I;d like codes for above all the others. I only own an NES reproduction of it, but I'd really like to get some codes for Summer Carnival '92: Recca

like the other shooters, I'm looking for infinite lives and possibly a way to keep your power ups.


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 21, 2008, 10:26:06 PM
Parodius da

infinite lives: GAOTTUZE

don't lose powerups: AVSKOASA

I haven't tested those too thoroughly, so let me know if they don't work.

Chuuka Taisen

infinite lives: XVVELGVK, XVVEGKEX (requires both codes)

don't lose powerups/specials: OVSEPGLY, this one skips a bunch of code, including the "you died" animation.  I played through to the second level and didn't see any bugs caused by it, but I can't guarantee it won't make the game crash later on...



Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 22, 2008, 11:27:11 PM
Sweet. Thanks so much uglyjoe. Can you do anything for Recca? I swear that game exists to mock you past the first level :P


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 23, 2008, 12:02:01 AM
Sweet. Thanks so much uglyjoe. Can you do anything for Recca? I swear that game exists to mock you past the first level :P

Try this for infinite lives: TASYXZVG

And try this to keep your weapons: YPSNNXIA, note that you will lose those spinny things that go around your ship after you die.  I'm sure there are instances where this code will not work, but I'm not sure when that is.  If you get to a spot where it's not working, let me know.

Dragon Spirit

This one is tough.  There are too many types of powerups to keep them all from de-leveling.  So, I'll give you these two that give you infinite health.  You shouldn't ever die with this one, so it's like having infinite lives:

XTVZOZVK, XTVZXZLS

The game gives you that little "pre game" level that will decide if you use the Gold dragon or Blue dragon.  Since you can't die, you'll always get the Blue dragon.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 24, 2008, 12:17:59 AM
Sweet codes uglyjoe! Thanks to you, I was able to beat Recca! Do  you know what it says at the end?

SUPER HARD SHOOTING GAME
               -RECCA-

followed by the Staff roll

I think that's pretty accurite!

and then you fight a boss and it says "To be continued"

Anyone know whats up with that? I didn't think Recca got a sequal?


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 24, 2008, 12:35:54 AM
Anyone know whats up with that? I didn't think Recca got a sequal?

Glad to hear that the codes are working.  The "to be continued" part is in reference to the second set of levels you get if you beat the game and hit reset.  Check this article:

http://hg101.classicgaming.gamespy.com/recca/recca.htm (http://hg101.classicgaming.gamespy.com/recca/recca.htm)

Getsufuu Maden - infinite health.

Infinite health: ATXKGNSA
Infinite lives (in case you fall into a pit): ZXXTOGYX, ZZVLAIYX


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on January 24, 2008, 04:14:48 AM
Sweet. Any codes for Gun-Nac (NES version?) looking for the usual: infinite lives, keep power ups. Becides Recca, Gun Nac is my favorite Famicom shump.


Title: Re: List of Game Genie codes

Sweet. Any codes for Gun-Nac (NES version?) looking for the usual: infinite lives, keep power ups. Becides Recca, Gun Nac is my favorite Famicom shump.

Infinite lives: OUOZYUSE, should work with either version.  I can't get a "keep your power ups" code to work.  Maybe some other night.

Gradius II

Infinite lives: OXUTTYVS

Invincible: ATENGIAZ, this is like the ultimate code.  You can't die.  You can fly through anything.


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 29, 2008, 01:43:37 AM
Konami Wai Wai World 1 - infinite heath. This game can kick your ass if you dont pay attention and its because of its difficulty that I dont like it nearly as much as its sequal.

infinite health: YOUGATGP

infinite lives: TEXTUPAE

Sword Master - just infinite health. wow this game's hard.

infinite lives: SXXTSOVK

infinite health may not be possible with a game genie...

AVKKKAAZ, ATVZAAEZ, ATOXYAEZ: with these three codes, you'll walk right through all the enemies and the bosses won't attack you.  It's pretty cheap, but if you want to see the game's ending, these will get you there (just don't fall into too many holes...).  The first one controls the enemies in the level and the last two control the bosses.  So, if you still want a challenge with the bosses, use only the first one.

Someday every Famicom game will have a page on FW and we'll have codes on them. Maybe sooner than later. By the way, this has turned out to be a cool thread. :)

Post by: satoshi_matrix on May 08, 2008, 08:33:30 PM
UglyJoe, could you please see if you cound find a copy for Devil World for Famicom to grant infinite lives? The life stock they give you isn't enough to complete the game. Thanks!


Title: Re: List of Game Genie codes
Post by: UglyJoe on May 08, 2008, 11:16:34 PM
NYVGNGIE = Start with 255 lives

XVNIAIEN + XVNIPITK = Avoid Game Over.  These two kinda avoid the game over screen.  It'll still say game over in the corner, but the game will keep going.  I don't know what kind of odd effects this might have later on (although I was able to go from level 1 to level 2 no problem).


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on May 09, 2008, 03:48:36 AM
Thanks uglyjoe. Any chance I could get either a infinite health or infinite lives or keep weapon after dying code for the Famicom cartridge version of Akumajou Dracula?

These are for the sake of my reviews, since I'm not using emulators and thus no savestates.


Title: Re: List of Game Genie codes
Post by: UglyJoe on May 09, 2008, 10:53:51 AM
Gonna be busy until Sunday/Monday.  I can get you some codes, but you're going to have to wait.

-------

OZOGZLVK = infinite lives

AVKTAYSA = infinite life

WONDERING.

If you plug an american game  genie into an nes, a converter into the game genie, and then a famicom cartridge, can you use the game genie with the famicom cart, using the famicom version codes?

Yes.

Post by: DDCecil on May 15, 2008, 08:13:30 PM
I had a code request, UglyJoe. it's for Ys for the Famicom. I'm just looking for a code for infinite health, or walk through solid walls. Either would be very appreciated, as I've searched all over the net with no results. Thanks!


Title: Re: List of Game Genie codes
Post by: UglyJoe on May 15, 2008, 11:22:49 PM
SZOTONSE - Ys, infinite health.  I only tried it out in the field above the first town, so there's a chance it won't work against other kinds of attacks (magic, etc).

To figure out a "walking through walls" code, I'd probably have to figure out how the map data is stored.  That's not something I plan on doing, so I hope the inf life code is enough.

UglyJoe, in his review/rant, the AVGN noted that Ninja Gaiden NES doesn't have an infinite energy code. Think you can whip one up?


Chinson, sorry for the late reply, but in case you were looking for more Earthbound Zero codes,  try out these. I don't take any credit for them, I just found 'em.

GTOLETAA
Start a new game with $100 cash.

XYOLETAE
Start a new game with $250 cash.

GAOLOTAA
Start a new game with about $1000 cash.

YZOLOTAA
Start a new game with about $10,000 cash.

LTKLUVTP + LTSLKVTP
Ninten starts with 99 HP (instead of 30).

XYKLUVTO + XYSLKVTO
Ninten starts with 250 HP (instead of 30).

ZLKLSVAA + ZLSLVVAA
Ninten starts with 50 PP (instead of 8).

LTKLSVAA + LTSLVVAA
Ninten starts with 99 PP (instead of 8).

PKOSNXZK
Get mega experience points after battle!

OUUXUPOP
Infinite PP (PSI).

ATSZEYPT
Get mega amounts of cash in your ATM when you try and
withdraw from it!  Do NOT deposit any money into your
ATM with this code on or else you may lose lots of
money from your ATM.

Title: Re: List of Game Genie codes
Post by: satoshi_matrix on February 18, 2010, 01:38:42 PM
Thanks UglyJoe, that code was really needed. Something else that comes to mind:

Since the PowerPak has 5 built in Gamegenie code generation and FDS support, is it possible to create Gamegenie codes for FDS games? If at all possible, I would like to request these codes.

Akumajou Dracula - Inf Energy

Metroid - Inf Energy

Super Mario Bros. - basically anything interesting. Since many codes exist for the NES and Famicom cart versions, this might be the one to test out possibilities with.

Super Mario Bros. 2J - Never loose powerups and inf lives.

Yume Kojo Doki Doki Panic - Inf lives

I wish you luck Uglyjoe!


Title: Re: List of Game Genie codes
Post by: UglyJoe on February 19, 2010, 01:27:57 AM
The Powerpak doesn't let you enter Game Genie codes for FDS games.  I was able to make GG codes that work in Mednafen and FCEUX, though:

Akumajou Dracula, inf health (depends on the FDS rom version):
ATSPNPSA (v1.2)
ATNOOPSA (v1.0)


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on February 19, 2010, 04:36:47 AM

Title: Re: List of Game Genie codes
Post by: nensondubois on February 19, 2010, 11:50:00 PM
Here's some codes I made when I was around 9 or so...

Super Mario Bros.
EPPPPP or PGPPPP
Unused song plays (It has been removed from SMAS and DX and in the .NSF there is a Bowser variation. I am the first to discover these!)
PPPPPP
Undergorund unused alt
XPPPPP
Underwater
SIPPPP
Starman
GAPPPP
Bowser's Castle

I like these unused songs.


Super Mario Bros. 2
TOLALL
Alternate soundtrack

Super Mario Bros. 3

Snow
ZXYOOK

ZKIPPEA
Rearranges game music

I can make GG codes so why not request them?


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on February 21, 2010, 10:09:14 PM
For the sake of finishing some of the outrageously difficult ROM hacks of the Rockman games, I would like to request Inf Energy, lives and weapon energy for each of the six Rockman titles. Back on page 1, Uglyjoe posted the inf Energy code for Rockman 2, so that's already done.

Rockman 2 infinite energy: SXOVTSSE  (this is the same as the SXXTPSSE code for Megaman 2). He said that he can convert any Megaman code to Rockman codes, so in the interest of making this request easier, here are the codes for each of the NES Megaman games I want converted to Rockman codes. Ones with ? question marks are codes I cant find any existing NES codes for. If you can generate NES and Famicom codes for them, that would be great.


Megaman 1:

Infinite energy - SZKZGZSA
Infinite lives - OZSKPZVK     
Infinite weapons energy - ?



Megaman 2:

Infinite energy - SXXTPSSE
Infinite lives - SXUGTPVG     
Infinite weapons energy - ?
Rapid fire - LZVSSZYZ

Megaman 3:

Infinite energy - GXVAAASA
Infinite lives - AEEGXLPA   
Infinite weapons energy - ?

Megaman 4:

Infinite energy - ?
Infinite lives -  SZUGUAVG   
Infinite weapons energy - GXENESOO
Instant Mega Buster - AEOAIEPA

Megaman 5:

Infinite energy - GXSEYZSA
Infinite lives - GXXAAIVG     
Infinite weapons energy - OVNLZISV + OTKPYISV


Megaman 6:

Infinite energy - ?
Infinite lives - SXEEXTVG   
Infinite weapons energy - ?


Title: Re: List of Game Genie codes
Post by: UglyJoe on February 22, 2010, 12:05:52 AM
Here's how you can convert the codes yourself:

  • First of all, just try the Megaman GG code in Rockman.  It might work without any conversion.  Failing that, though:
  • Open up Megaman in FCEUX.
  • Goto Debug -> Game Genie Decoder/Encoder...
  • Type the Game Genie code you want to convert into the Game Genie Code field.
  • Write down the values of the Address, Compare, and Value fields.
  • Hit "Add To Cheat List" and close the dialog.
  • Get to a point in the game where the code becomes relevant (like, get into a level, not on the title screen or stage select screen) and hit the Pause button on your keyboard (this is an emulator pause, not the in-game pause).
  • Goto Debug -> Hex Editor...
  • Scroll down to the address you wrote down in step 5.  The affected byte should be colored blue.  Write down the three bytes before it and the three bytes after it.
  • Open up the Rockman rom in FCEUX now (we don't need Megaman anymore).
  • Get to a point in the game where the code would become relevant (ie, in-stage) and hit the Pause button on your keyboard.
  • Goto Debug -> Hex Editor...
  • In the Hex Editor dialog, goto Edit -> Find...
  • Make sure Direction is set to "Down" and Type is set to "Hex".  In the "Find What:" field, type in the first three bytes you wrote down in step 9 (no spaces, upper/lower case doesn't matter), then the Compare value you wrote down in step 5, and then the last three bytes you wrote down in step 9.  Hit the "Find Next" button.
  • The Hex Editor should highlight the seven bytes you searched for.  Click on the one in the middle (it will be equal to the Compare value).  In the titlebar of the Hex Editor dialog, you'll see "Hex Editor - Editing RAM Offset 0x00ABCD", where ABCD is some hex address.  Write down that address.
  • You can close the Search and Hex Editor dialogs now.
  • Goto Debug -> Game Genie Decoder/Encoder...
  • Type the address you just wrote down in step 15 into the Address field.  Type the Compare and Value values from step 5 into their respective fields.
  • After you've typed in those values, the "Game Genie Code" field will populate.  There's your converted Rockman GG code.  You can hit "Add To Cheat List" if you want to test it out.

Post by: satoshi_matrix on May 17, 2010, 05:24:16 AM
Here's a pretty awesome GG code I found for SMB3. I've tested it only on the NES version.

AOSUZI - Block Suit Mario

Press B at anytime and Mario will generate a toss-able block normally found in only certain stages. The game will think Mario is grabbing the block from whatever tile is next to Mario's hands and strip it down to the bare background tile. This means you can rip and remove background elements such as hills or clouds as well as solid stage objects such as coin blocks and warp pipes!  With this code you can literally tunnel your way through a stage!

Only problem that I've found is that it causes the game to crash unexpectedly.

Uglyjoe, I wonder if a GG code could be made to correct the crash issue?


Title: Re: List of Game Genie codes
Post by: UglyJoe on May 17, 2010, 01:27:21 PM
Uglyjoe, I wonder if a GG code could be made to correct the crash issue?

Possibly.  It depends on what's making it crash.  If I had hours to spend staring at a trace log I might be able to figure it out, but there are other things I'd rather do ;)

Hi guys, I have seen that some of you are really good at finding game genie codes for games, and I would like to ask you for help finding some for the loopy's MMC3 hacked SMB2j version (you can find it on his site (http://home.comcast.net/~olimar/) in the NES section).

THANKS! If you cannot find the level select code, try to find at least the infinite lives code.
...yes, I suck at SMB2j on NES/FC, it's hard as hell! But for some reason I've managed to play untill W7-3 on my SMB deluxe - GBC version. But there was a save game option.

So I've been playing around with this and it doesn't seem to be working. Maybe someone who has more experience with this might be able to understand why or get around it. For some reason when I put the address I want to modify into the game genie code creator and create the code, then look at the code later, the value is changed and the code is worthless. Like, for example, if I wanted to make an infinite lives code, I should modify address 701B and change instruction CE to AD... Yet when I look at the code afterwards, it says it's modifying address F01B instead, and the code is worthless. This is where the debugger says the change should be made. I can't change the instruction if it keeps picking a different value for the address.  >:(

Thanks.

The NES PRG-ROM exists from $8000 to $FFFF.  As such, Game Genie was designed to only allow you to make changes to that memory range.  You can't modify $701B because it is not in that range.  The reason why code is being executed outside of that region is because MMC3 uses the SRAM space ($6000 - $7FFF) as a PRG-RAM region.

Now, because $701B is ram, that means that its value (CE) must have been written to it by some other routine.  Set a write breakpoint at $701B and do a hard reset.

When the debugger snaps, you can see that the accumulator, which is holding the value CE, is being stored into $701B.  If you look at the previous line, you can see that it loaded the value into the accumulator from $D01B.  Lucky!  Since $D01B is within our PRG-ROM address space, that means we can change it with Game Genie.

Make a code that changes $D01B from CE to AD and you get SZOSLEVK.  Try it out and you've got infinite lives!

Here's a bootleg stage-select method.  Use these codes to pick the starting world and stage.  I'm not sure how to get to the A-D worlds:

world:
1: AENKAGAA
2: PENKAGAA
3: ZENKAGAA
4: LENKAGAA
5: GENKAGAA
6: IENKAGAA
7: TENKAGAA
8: YENKAGAA
9: AENKAGAE

stage:
1: AENKIGAA
2: PENKIGAA
3: ZENKIGAA
4: LENKIGAA
These seem to only be cosmetic...

Oh man UglyJoe! That explains a lot. I had a vague idea that the MMC3 was involved, and that this value must be outside of the Game Genie's memory range.. I didn't know what the range itself was, nor did I know how the MMC3 worked, but this has explained why a rare couple of gmaes in the past have been Game Genie unfriendly to me.. This is why I'm doing this though, to learn.

I've learned more about how a computer works by playing with Game Genie codes than I ever did taking recreational programming classes in school.

UglyJoe or anyone else, can you come up with some code to address this problem?

Something like

No Random Encounters

or at the very least, always be able to run from random encounters would be very helpful.

Post by: UglyJoe on December 19, 2010, 04:45:23 PM
Okay, I made these using a "Mother (J).nes" rom, so I hope that's the one you're playing.  Couldn't find a one-code way of doing this.  Note that these codes seem to cause some glitches in certain text boxes (like the Game Over text) and I have no idea why.

The game seems to generate a pseudo-random number after every step you take (but also at other times, it seems) and then checks to see if that number is less than some other number, which I call the "encounter rate" for lack of a better name.  There is a small table of encounter rate values and I'm assuming the value used depends on the area you are in, but I didn't look into that part of the code too much.

These codes will hard-code the encounter rate to a fixed value.

Use both of these codes, which make the comparison use a hard-coded value rather than the lookup table:
OGVPYSSS
XTVOPISO

And then one of these codes.  A lower number means less random encounters.  (00) means no random encounters, although if that's what you wanted then I could probably do that with less than three codes.  As a frame of reference, the area just outside of Ness's (Ninten's?) house is using (13), and it looks like the toughest areas would be using (32).

GAVOAINO (12)
LAVOAINO (11)
ZAVOAINO (10)
PAVOAINO (09)
AAVOAINO (08)
YAVOAINP (07)
TAVOAINP (06)
IAVOAINP (05)
GAVOAINP (04)
LAVOAINP (03)
ZAVOAINP (02)
PAVOAINP (01)
AAVOAINP (00)


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on December 21, 2010, 02:51:05 AM
Thanks UglyJoe. So that I understand what you're saying, In order to completely remove random encounters, I need to put in three codes:

OGVPYSSS
XTVOPISO
AAVOAINP

And the difference between say

AAVOAINP (00)

PAVOAINP (01)

is that with the first code will never produce random encounters while the second code will almost never produce random encounters?

You said you could probably produce a code that turns off enemy encounters completely in less than three codes? Please see about that. This is exactly what I'm after, as long it doesn't affect scripted encounters (such as the lamp battle at the very start of the game) or encounters you seek out (such as the doll battle also at the start of the game).

I would like to ask about inserting the GG codes into ROMs:
SMB has this invincibility code: ZZZSSO
This code should alter the value on adress 0xD92D to value 2A
but the ROM size is only 0xA00F (including the 16byte header).
So how do I alter the adress which is out of the file size? Thanks!
(By the way I need this also for code VZTLTN altering 0xB766 to AE)


Title: Re: List of Game Genie codes
Post by: UglyJoe on January 08, 2011, 02:41:01 PM
Because SMB1 doesn't do any bankswapping, you can do this:

Code:
0xD92D + 0x10   ; offset iNES header
0xD93D - 0x8000 ; offset start of NES PRG-ROM space
0x593D          ; address of byte you want to change


Title: Re: List of Game Genie codes
Post by: jpx72 on January 08, 2011, 03:24:29 PM
Great! It works (obviously)!
So add the lenght of the header and substract the lenght of the PRG part... Hopefully one day i will understand why :D
Thanks a million UglyJoe!

Title: Re: List of Game Genie codes
Post by: UglyJoe on February 10, 2011, 02:55:34 AM
This one is a bit weird.  There are three places in the game's code that check the "how many stars should they have" byte (which is stored as the first byte in the SRAM at 0x6000).

VXEGZGAV - The "functional" code.  This one will give you 24 stars, but you don't see them on the title screen.  If you hold down A when you press start, though, you'll be in World A.

VZUYXZAV - The "cosmetic" code.  This one will light up the title screen with 24 stars, but as far as I can tell it's just for looks.

VXXKYIAV - The "mystery" code.  This modifies part of the game code that looks at the "stars" byte, but I have no idea what it does.

You can use them in any combination that you want, as they should work independent of each other (except maybe the third one, since I don't know what it actually does...).  I figured 24 stars was better than 7 or 8, but if you specifically need 7 or 8 stars there, I can come up with codes for those, as well.


Title: Re: List of Game Genie codes
Post by: jpx72 on February 10, 2011, 04:42:26 AM
May I jump in with something different?
I have a question from the other end: There are two versions of hacked FDS version of All night nippon Super mario bros rom to work on cartridge:
All Night Nippon Super Mario Bros. (J).nes
All Night Nippon Super Mario Bros. (J) [a1].nes
The ONLY difference is at h9B6F where the first one has hEF and the second [alternative] has h6F. What does this difference do? It's definatelly nothing obvious because I can't tell from playing those two versions for some time. Maybe it's just some mistake that occured during dumping the pirate rom, and maybe it doesn't affect gameplay at all. Can this be discovered by any mean? Thanks!


Title: Re: List of Game Genie codes
Post by: UglyJoe on February 11, 2011, 01:14:36 AM
When you're looking for small changes like this based only on a single address, the first thing to do would be to determine if it's program rom or character rom.  A quick glance at the rom in a tile editor shows that the address 0x9b6f is part of the CHR-ROM, so it's just a graphical change. 

The difference is a single pixel in part of the stone floor graphics, as shown below.  I've marked the different pixel with a blue pixel so it'll stand out better.  You can see after I stop marking it that it is indeed a different color between versions.

(http://ximwix.net/storage/annsmb.png)

And here they are side by side, notice the bottom-left pixel

Title: Re: List of Game Genie codes
Post by: jpx72 on February 11, 2011, 04:56:32 AM
Wow you really ARE a genius Joe! Thanks! I would have never found out what's the difference, and it would bother me for a VERY long time! I would say that the A1 stone texture version looks a little better than the first one, but it's such a small diference that I actually think it's only a mistake. And a mistake that got an [a1] tag and it's spread over the internet.

Also great job on the stars-code for loopy's SMB2j! Always appreciate a new code for my repro! :D

Post by: gorgyrip on February 11, 2011, 05:13:39 AM
UglyJoe, thanx for the codes. i tested them on a real nes.
VXEGZGAV - The "functional" code.  It works, but the game freezes sometimes. for exemple when i was at the end of world A-1, or when i paused the game in A-1 to go for a smoke. It's random. i don't know if it's a bad connection between the nes-game genie-game, or maybe the rom, or even the code.

VZUYXZAV - The "cosmetic" code. - This code didn't worked.

if you please, can me make a code to have 7 stars. why 7? because i want to make another cart whit the code patched in the rom. and that way you can acces world A-1 only when you finish the game one time.  it's not important if the star are visible or not at the title screen.

Would have been helpful to know this at the beginning!  So you don't really want 7 stars, you want to be able to get to World A after beating the game only once.  Those are two different things.  I can make a code for that.

Tested on NTSC version of SMB1, haven't tried them on european version yet.
NNXAZZYE + AANAAXZG
(Allows you to go to any world you wish, even after world 8, so you can explore all 256 worlds in a game)
SOSENA (Graphics are messed up)
POPAYA (Graphics are messed up along with the screeen where it says how many lives you have)
ENEPIP (Star Mario + No Power-up on title screen demo. Timer goes to 1000 and timer doesn't reset if you die. After dying, Mario looks like he got a star)

If it helps, Megaman 4's original Game Genie code for infinite weapon energy (GXENESOO) did the job pretty well EXCEPT for the Rush Adaptor and the Balloon Adaptor (Wire is unlimited already). Although it worked for Dive and Ring, it screwed them both up in a couple game-breaking ways:
1.) It would randomly deplete your weapon energy completely
2.) If you died, you completely lost both of the weapons even if you already beat the boss.
I think it has to do with the fact that both Dive and Ring have an ammo capacity of >28 (Ring being 56 and Dive 72), but I'm just spitballing here.

I appreciate you taking the time to do this and I hope I helped! ;D


Title: Re: List of Game Genie codes
Post by: UglyJoe on July 07, 2013, 01:30:09 AM
Using the save file that you PM'd me, I came up with OZNNKSPX (mmc3).  This is giving unlimited weapon energy for everything in the save file except for the Rush Search (which, I guess, you can use this code and the one I gave earlier at the same time...haven't tried).

2.) If you died, you completely lost both of the weapons even if you already beat the boss.
I think it has to do with the fact that both Dive and Ring have an ammo capacity of >28 (Ring being 56 and Dive 72), but I'm just spitballing here.

This happened to me once, and I wasn't using any other codes.  Don't know if it was a residual effect in your save file or if it was my GG code. :-\

Post by: TheDoc on July 07, 2013, 05:44:51 PM
Ummm,..this actually made the weapon disappearance worse for me. If I completely lost my ammo on Dive, then switched it out for another weapon, Dive would be gone forever. Also, if I died, Balloon AND Dive would be gone. I'm going to try it on FCEUX (I'd been using VirtuaNES up to this point) to see if that helps.

RAW    
0046:F0
RAM Write - Constantly writes 0xF0 to the RAM address 0x46.

Since it's also a RAM address, does that mean I can't add it to say FCEU's cheat page (I've tried the F0 on Value and COmpare, but they always turn to 0):

Right.  You'd have to use a debugger to find out what part of the code (which is in the ROM address space) sets values to 0x0046 and change it to set it to 0xF0 instead.  That's an over-simplified explanation, though :-[

I just finished my first play through of the incredible Zelda 1 hack, Legend of Link.

I’m planning on writing an article about it for my blog and plan to capture specific screenshots for it, playing it through a second time at an execrated rate now that I’ve played it through.

UglyJoe or someone else, could you please generate a Game Genie code that would allow me to walk anywhere in the overworld? A “walk through walls” code as it were. This would greatly speed up the process of playing through the game with screenshots.

Thanks for any assistance.

Not sure I could pull it off using Game Genie codes.  I figured out how to "warp" Link around the screen by poking some memory addresses, so that I can get to any edge of the screen and walk to the adjacent screens.  If you use FCEUX, I could write you a LUA script to get you around.

Post by: satoshi_matrix on April 20, 2016, 12:12:59 AM
UglyJoe, I've got something else I'd like to request your help with.

Could you see if you can come up with codes to disable hit detection for all six Rockman games and possibly their US Megaman counterparts as well? This is especially important for Rockman 2, but I would like the same code done for the others as well if you can manage it.

The reason i request this is because I'd like to a mapping series of Megaman ROM hacks, especially for the more elaborate hacks. Make level maps to both admire what the hacker was doing and also be able to write up strategy guides for the most difficult hacks.

For the mapping portion, I need to make sure Megaman can move through enemies and enemy fire as if it isn't there.


Title: Re: List of Game Genie codes
Post by: UglyJoe on April 20, 2016, 03:08:35 AM
For Rockman 2, you can use both:

ATSTYSOZ AVOVTSSA - works in levels
ATXXISOZ ATNZPSSA - works on bosses

I only tried this on three levels and two bosses.  Instant-death traps will still kill you.  I doubt these will work with advanced rom hacks, though.

(updated the codes with ones that still let you pick up powerups and seem to cause less glitches)


Title: Re: List of Game Genie codes

I haven't looked at Megaman 2.  Those same codes might work.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on April 20, 2016, 07:14:17 PM
They don't seem to work for Megaman 2, only Rockman 2. Can you see if you can adapt the codes to work with MM2?


Title: Re: List of Game Genie codes
Post by: UglyJoe on April 21, 2016, 01:24:54 AM
Try these two for Megaman 2:

ATSVZSOZ AVXTPSSA - for levels
ATXXISOZ ATNZPSSA - for bosses

The first one seems to screw up some of the graphics in the opening sequence, so if you see weird stuff while playing, you may need to temporarily disable the cheats.  (This was probably true with Rockman 2, as well, but I didn't check).

(updated the codes so you should be able to pickup powerups now and they don't seem to be as glitchy)

FYI, these codes end up skipping entire routines.  The logic that says, "you've been hit" is getting skipped, but there's a possibility that other stuff is being skipped too.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on April 21, 2016, 03:25:32 AM
Truly excellent. Thank you. Could you please see if you can do the same for Rockman 3 and then Megaman 3? I would imagine that the engines are very similar for all six games, so hopefully this won't be too difficult. I'd like this done for all six Rockman games, but 2 and then 3 are the top priority.

Thanks!

I've also got another request. In Rockman 2, is it possible to generate a GameGenie code to mute sound effects, but not music? There are a number of hacks that use custom music, and I'd like to record it without sound effects getting it in the recording.

Thanks! Lastly, can you see if you can get a code for Rockman 1 and Megaman 1?

Yes, nsfs would be preferred, but again I want to record custom music from custom hacks. There are no nsfs available.

and the Rockman games don't have sound tests, so the only way to record audio is from the game running. But there's a sound effect as soon as Rockman appears onscreen, and sometimes there is an enemy right away as well. So if theres a gg code that could be whipped up starting with Rockman 2 that would disable sound effects, that would be be great.

Title: Re: List of Game Genie codes
Post by: satoshi_matrix on April 30, 2016, 04:38:17 PM
The spacing doesn't exist in Japanese. It was done in English I guess to help kids more easily pronounce the names. Megaman to a child is harder to read than Mega Man. I will frequently ignore the spaces whenever talking about Rockman as well. I suggest you do the same, just pretend they don't exist.


Title: Re: List of Game Genie codes
Post by: P on April 30, 2016, 06:35:04 PM
I just checked the first game (both Japanese and English versions) and there are no spaces, they are all Elecman etc. I guess people have started adding spaces in the robot names just to make them match Rockman's localized name.

UglyJoe, I've got another request. Last time, I asked if the sound effects for the Megaman games could be muted, leaving only the BGMs. Now I'd like the opposite. Leave all sound effects, but mute all background music. Could you please start with Rockman 2 and the US Megaman 2, then the US versions of 3, 4, 5 6? Thanks! you're a real hero and wizard at this.

ATKAGASZ - Rockman 2, no music (SFX only).

Did the Rockman 2 "no sfx" codes work for you with any rom hacks?


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on August 26, 2016, 04:06:06 PM
Alright!  ;D
The same code works for both Rockman 2 and Megaman 2. I just did most of a playthrough and it appears to be working. In case you're wondering, this is so I can record footage, insert custom music and still retain the sound effects.

And yes, the previous removal of sound effects only worked for every rom hack I tried.

Next, please see if you can come up with the same no music, sfx only code for Megaman 3. Rockman 3 might even be the same code.

UglyJoe may I ask you for help making a working IPS patch for japanes Gimmick with unlimited lives?
It's been a while and I don't remember how it's done, I found a code
SUTTTS
but when I "insert" the code into the rom with software "Game Genie Guy by Kyle", the output rom has glitches (on the START screen you can see a small black glitch flying over, and one music chanel is out of sync after a while).
 I don't even know if the code is correct but it's working in Nestopia, at least in first level, I found a forum where somebody said you must not die in level 2 or the game freezes.
Maybe a 99 lives code would be better (safer and glitchless) than an unlimited one.
Thanks!


Title: Re: List of Game Genie codes
Post by: UglyJoe on September 14, 2016, 07:21:28 PM
I can tell by the code's length that it's not doing a comparison check, so it's likely to cause bugs in a game as large as Gimmick.  I'll take a look at it tonight if I get a chance.

Edit:

SXVTTSVK - GImmick! Infinite lives

The SUTTTS code targets the same address as SXVTTSVK, but since it doesn't do a comparison check it ends up modifying 32 bytes instead of 1 byte!

It sounds like you know how to make IPS patches, so I'll leave that to you.

I'm still looking to see if it's possible to mute the BGM in Megaman 2 (GB) and retain the sound effects. I asked about this on nesdev and got what may be a promising lead:


"I don't know GB assembly enough to look at the ROM, but there's a possibility this could work:
get the GBS rip
get the music play routine, disassemble it to find out if it's a code stub added by the ripper (for the init it probably is, so get the real address from this code)
replace all the calls to that address with NOPs

If removing play doesn't work, try the same thing with the init address instead.

But if that same address initializes/plays sound effects too, or is otherwise still needed, then it's going to be significantly more complicated."

So with that in mind,


The Megaman 2 GBS file can be found here:
https://ocremix.org/chip/342

and the original rom for disassembly purposes can be found through a simple google search. Not gonna direct link to it in this case.

Hopefully there is someone out there with the knowledge to do what was suggested with these files.




Title: Re: List of Game Genie codes
Post by: UglyJoe on September 25, 2016, 12:47:04 PM
That's essentially what I tried to do.  It does appear that the same routine is used for both music and sound effects, so I couldn't just disable the routine (it mutes the entire game).  I tried to separate the music calls and the sound effects calls, but I couldn't get it to work properly.  I did get it to only play SFX and not music, but the SFX were messed up.  It seemed to me like the SFX won't work properly at all unless there is music playing, but I didn't take the time to disassemble the audio routine.  (I'm not familiar enough with the gameboy's architecture to do it, and even if I were it would be very time-consuming).

I'm not experienced enough with the GameBoy to say one way or the other.  I would guess that somebody more familiar with it than me could figure it out if they put in the effort.  I do think it would involve figuring out how the sound engine works, though, which is no simple task.

Here is something I have wondered for a long time, since back in 1999 or so.

Regarding Castlevania III:  Is it possible to use a Game Genie code(s) or create a password of sorts, where Trevor Belmont is replaced by one of the spirit helpers?  For example, having Sypha and Grant (and no Trevor), or Alucard and Sypha, etc.  I wouldn't see why it wouldn't be possible to replace Trevor with one of the other helpers, having two special characters without the Belmont, but thus far I have never seen any code about it, and I just play games, don't create them, so maybe I am expecting the impossible?

I've never looked at the game's code, but my guess is that Trevor is sort of hard-coded in such a way that you can't remove him from the party.  I'll take a look later if I get a chance.

Edit: Looked into it a bit.  I don't see a way of doing it by only changing three bytes (the standard limit for number of Game Genie codes).  I'm pretty sure I could do it with a plain ASM hack, though.

If you combined multiple Game Genies, do you think it would be possible?

Does that even work?

I found a new approach to take last night after I posted, so I may be able to get it in three bytes or less after all.

I know you can use multiple Game Genies to make more than 3 changes / to combine codes.

If you can figure out some Game Genie method to get this to work, I'll send you a nice goodie package as a reward ;)  It's always been my dream, something like this.

Flashcarts usually gives 5 Game Genie codes or something. But it might still not be possible to do by just changing 5 bytes.

Regarding Castlevania III:  Is it possible to use a Game Genie code(s) or create a password of sorts, where Trevor Belmont is replaced by one of the spirit helpers?

Okay, I managed to get this to work using a combination of cheat codes (special user names at the name entry screen) and game genie.  I would consider these "beta" codes, since CV3 is a complicated game and I didn't test things out too much.  These are for the US version of Castlevania III.  I'll test them / convert them for Akumajou Densetsu in a bit. Akumajou Densetsu does not seem to have name cheats like the US version, so I'm not sure I could do it.

PartyNameGame Genie
Grant + SyphaFUJIMOTOSEXPTAEI + PUXPYATE
Grant + AlucardFUJIMOTOSEXPTAEI + PUXPYATE + LEXOPAPA
Sypha + AlucardURATASEXOZAEI + PUXOLAZE

You'll still start out as Trevor, but once you switch characters he should be gone for good.

Now that's pretty cool! I'd never thought to try CV3 without the Belmont, but now I'm going to have to give this a playthrough. Thanks!

When you get a chance, could you please see about BGM muting in the NES games I mentioned above? Thanks.

Megaman/Rockman 1
Gradius 1
Super Mario Bros.
Salamander (or LifeForce if you can't do Salamander)
Castlevania 1 NES
DuckTales 1
Dr. Mario


Title: Re: List of Game Genie codes
Post by: UglyJoe on October 07, 2016, 12:25:47 PM
Yeah, I saw your list.

Megaman/Rockman 1 - No music - ATKOIAEL

Gradius apparently uses its SFX engine to play back certain overture type tunes.  Like when the game starts, you hear music but no sound effects, but eventually the song loses a little depth and then you hear your sound effects.  With the BGM disabled, you still hear those overture things.

Gradius (J) - No music - USSVOGTV
Gradius (U) - No music - SXXVUKAU

Great. No rush on all of them, just one at a time at your pace. Thanks! :)


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on October 17, 2016, 01:25:49 AM
These are great. I was hoping that Gradius 1 wouldn't have that problem but I speculated that would indeed be the case which is why sound effects don't play as soon as you start the game.

The Megaman 1 codes are very useful. Now I can do that Touhou project I had been planning. Many thanks.

Could you please look into Castlevania 1 (NES) next? Thanks.

Preliminary codes:

XXKGTZVZ
EEKGYXAZ

This mutes the stage BGM, but the incidental stuff (intro, boss music, game over, ending [probably]) still plays. 

Too late for Halloween, though :-[

Thank you! Even though its late it still is very much appreciated. This will let me do some Castlevania stuff I've wanted to do for a while now. This will be a great result.

The next ones that I'd like SFX only codes for:
 
Super Mario Bros. 3
Final Fantasy 1
Contra
Earth Bound
Super C

Thanks!

Here's some Game Genie codes for Moai-Kun:  :)

PEEOZYGT - Fall from high places without getting hurt.
SZELGYVG - Infinite Time

LOSTVYLA - Doesn't really help with anything, but enables horizontal side-scrolling in level 3. (There is unused code for horizontal side-scrolling, but it isn't used without hacks or game genie codes)

I also made a bunch of Game Genie codes, one for each level, so you can start on any level you want. I don't remember where I saved them, but later I'll try and find them.

Also, could someone make a Game Genie code for Super Mario Bros. that prevents you from getting extra lives? (Both by 1-ups and by getting 100 coins). I'm making a ROM hack where you have infinite lives, and I want to combine the code that prevents you from losing lives with a code that doesn't let you get lives.

There's these 2 GG codes for the Japanese version of Final Fantasy IIj (NES):

Walk through walls in towns/dungeons:
AAXGVKZZ
Walk faster in towns and dungeons:
ZEVIZGPA

Is there a way to convert them to work on the U.S. Prototype version? Most codes already work with it, but these 2 don't unfortunately. Thanks!

Do either of these codes work for you with the Japanese version?  They don't seem to be working for me.

Hmm, both codes work fine for me on the normal FF2j ROM and the FF1 and 2 combo cart ROM:

I've found sometimes it depends on the revision. I couldn't get the Castlevania codes to work until I tried a totally different rom. My actual cart won't accept them.

UglyJoe, when you get a chance, please see about a code for Super Mario Bros. 3. I don't know if youtube will block it without the music. It'll be interesting to see what happens.

Sorry about that.  I wasn't done making the codes, so I didn't try both roms (there is a PRG0 and PRG1 version).

Sure.  But I guess there's also the case where you get a 1-up by jumping on enemies repeatedly?  And also one for using the same turtle shell to kill a bunch of enemies?

Yeah it's ok. That sort of thing doesn't really happen very often in my ROM hack, as far as I know. :)

That wasn't in the original SMB, I'm 99% sure.

Ah yes I'm pretty sure it's in SMB2j only. Something about jumping on the flag at a certain value of the timer.

Sorry, man, I don't think I can do these for you.  These aren't easy like most of the other requests.  I enjoy making them, but they take too much time/concentration, neither of which I have much of recently.

I had started looking into SMB3 (since, amazingly, there is a disassembly for that as well), but did not get a chance to complete it.  I'll be pretty busy throughout December, so I don't think I'll be able to make any codes until the new year.

Hey I found the "start on any level" codes for Moai Kun I made. :)
I wrote a computer program to make codes for levels 0-255, although there aren't that many levels in the game. :P
Level 0 will crash, and levels after the last level will be kind of glitched, with weird objects and stuff.
I would take out those codes, but I don't remember how many levels the game has.

Here's the list (in a spoiler because it's really long):

Start on level 0: AESEGZPA

In some rare cases you can get stuck in walls (mostly boundaries of the level). Use these two codes to prevent that in some cases:
OXEUAYSE
OXUTPLSE

Games gives you max speed instead of making your speed 0 when stopping to the right. It's only purpose is glitching the game especially together with walking through walls:
YNOYLTAE

I had started looking into SMB3 (since, amazingly, there is a disassembly for that as well), but did not get a chance to complete it.  I'll be pretty busy throughout December, so I don't think I'll be able to make any codes until the new year.

Thank you so much. I eagerly await the results. SMB3 is a huge amount of potential through romhacks, not the mention the core game itself.

Hey, could you try to make a code for Super Mario bros that lowers the amount of time the game spends on the screen that shows up when you die or start a level?

I was trying to make it myself but i can't get it to work. :(

SMB3 - No BGM - ATKVYUSZ

Seems to work on the four variants of the rom I have (U PRG0/1, J PRG0/1).

ZEXAVAYA will shorten it down quite a bit.  What you're really doing is "88a6 07 -> 02".  In other words, change code at address 88a6 from 07 to 02.  You could set it higher to wait longer or lower to go faster.  AEXAVAYA sets it to 00 so it just blinks that screen at you.

ZESAGTZP can be used to similarly shorten the "game over" screen (86d4 12 -> 02).

What about Final Fantasy 1 or Earth Bound? Can you see about either of those? Thanks.

Final Fantasy also has a disassembly, so it wasn't so bad:

FF1 - no BGM - AVOUPASZ

Tested with the US rom and the two Japanese roms.

Thanks so much for the no music in SMB3! That's AWESOME!

A while ago, I asked for some codes for Rockman 2 that make Rockman impervious to enemies and shots, effectively removing collision detection.


There a rather crazy impressive Rockman 2 rom hack that does something to prevent the codes that work the original rom from working.

Rockman CX patch can be found here: http://www.romhacking.net/hacks/3231/


I don't know if this is impossible, but could you take a look a look and see if you can figure out how to get the same walk through enemies/bullets effect working for this super tough rom hack? I want to fully explore it without having to reload save states every five seconds. Thanks!

Here were your original Rockman 2 walk through enemies codes:
AVOVTSSA - works in levels
ATNZPSSA - works on bosses

Having played through half of Ganbare Goemon 2 and not wanting to start over, I created some Game Genie codes to start off on different stages:

Ganbare Goemon 2:
TAEIOGPA - Start on Stage 2
PAEIOGPE - Start on Stage 3
TAEIOGPE - Start on Stage 4
GZEIOGPE - Start on Stage 5
YLEIOGPA - Start on Stage 6


Okay, nevermind. After completing a stage, it assumes you beat stage 1 and moves on to stage 2. Can anyone help me figure out how to do a stage skip properly?

Using the cheat search on FCEUXD, I found that address 07B4 is the current stage (00=stage 1, 01=stage 2, etc.). I plugged that into the debugger, but could not find any breakpoints.

Hey UglyJoe, I saw a video on youtube that explained the ugly leftmost vertical bar in many NES and Famicom games is a CPU-controlled mask layer used to better hide swapping of nametables.

Is it possible to disable this through the use of GameGenie?

It's present in Super Mario Bros. 3, Megaman 3-6 and many others. Think you could whip up codes to remove it? I'd just like to see for myself what the result would look like without the line, especially for Megaman 3-6.


Title: Re: List of Game Genie codes
Post by: P on April 10, 2017, 05:25:15 AM
Sounds like you are talking about bit 1 and 2 of register $2001. Both bits, when zero, hides the leftmost 8 pixel columns of background and sprites respectively for bit 1 and 2.

If a game is using the mask, I guess it's to hide some ugly artefacts that results from scrolling or something, so it might not be pretty to remove it. But it would be interesting to see how it looks. I tried simply forcing the bits to 1 in SMB3 in FCEUX but the game is updating the register every frame so my changes was overwritten immediately.

I guess a Game Genie code should do the trick.

It depends entirely on how the game is coded.

It's present in Super Mario Bros. 3

So you want to see the ugly artifacts, then?

TPUYLSAO
TPVNXEAO

That'll work for level 1-1 and possibly others.  It would probably take too many codes to patch the whole game.

Rockman 3:

TPSYNVAO
TPUKTSAO

Rockman 4:

TPSNNVAO
TPNGTUAO

Rockman 5:

TPSNNVAO
TOSKTXAO

Rockman 6:

NYNKIEON

Post by: satoshi_matrix on May 05, 2017, 08:40:46 PM
This is real interesting stuff. Seems like in a lot of places Capcom didn't even bother making the leftmost eight pixels correct in many places - they are garbaged parts of tiles or else just glitchy.

This brings up a second question. Why is there a need for a two line code for all but Megaman 6? What's different about Megaman 6 compared to say, 5 that allows it to get the same effect from a single line of GameGenie instead of two?

I don't have the time to look up the code right now, but I can assure you that it is nothing really notable.  I think 3/4/5 bit mask the PPUMASK in two places and 6 only does it in one place.

I remember from the sound hacking GG codes that 3/4/5 have a very similar engine (the same GG code worked for all three) and then 6 needed a different code since it seems to use a new (or altered) engine.


Title: Re: List of Game Genie codes
Post by: P on May 05, 2017, 10:28:09 PM
In other words, one Game Genie code changes one byte, all Rockmans except 6 needed two bytes to be changed, so they got two codes, while Rockman 6 only needed one byte to be changed.

I tried the code for SMB3. It has lots of scrolling artifacting as it is, when removing this mask it gets much worse.

Thanks for that explanation.

Can you disable the BGM in these? I came across some nice rom hacks that I want to overlay with my own bgms. I'll list them in order of priority.

Bomberman 1 (Japanese version if it matters)
Mappy
Challenger
Ice Climber
Donkey Kong
Dig Dug II
Binary Land
Atlantis no Nazo
Nuts & Milk
Dig Dug
Spartan X
Pooyan
Clu Clu Land

Bomberman (JP):
No BGM: AUXTIKOK AUXTTKLE

This also makes the "STAGE X" screens flash by rather quickly, since I guess it's programmed to wait until the song is over before moving on, but since there's no song it just moves right along.

Can you see about an adjusted code for the Famicom cart version of Akumajou Dracula released in 1993? Found a hack that uses that version and need to mute the bgms.

Can I ask - what do you use the no BGM codes for?  YouTube playthroughs or do have otehr music on in the background?
 
I was playing Sonic Mania the other day and had a no BGM glitch kick in, and it was really nice to hear all the SFX that are usually missed to be honest.  
 
It did feel different.  I suppose ou can always turn the music off in that game anyway though (or at leats right down).

Try playing the Rockman games with no music.  It feels like a completely different game.


Title: Re: List of Game Genie codes
Post by: satoshi_matrix on August 26, 2017, 04:25:51 PM
Since the Famicom only has four sound channels total, sound effects and music must both use the same resources, which often lead to them clipping each other.

I'm looking for no bgm codes for Gradius 2 and Salamander, please and thank you.
