Hello,
For a long time, I wanted to have an ultimate famicom/fds/nes system, that includes :
- nes cartridge support,
- famicom cartridge and famicom disk system support,
- RGB video output.
To do so I took :
- a NTSC nes console, with region lock ship disabled,
- a 60 to 72 pins cartridge converter, I found mine in US version of Gyromite,
- a PPU RGB video processor, took from a nintendo playchoice 10 arcade system.
Some US Gyromite cartridge hide some very interesting stuff.

Once opened, the cartridge reveals the famicom pcb of Gyromite, plugged into a 60 to 72 pins converter :

That 60 to 72 pins converter can be used with every famicom game :

I decided to add that converter to my nes, in order to make it as an hybrid that can play both famicom and nes games.
I soldered the converter to the nes motherboard, precisely on the 72 pins egde. The easiest way to do that is to solder all signals on the component side of the motherboard :

Next, the famicom connector needs to be fasten :

Some test before reassemble the nes :

Good :D
Once reassembled, "FamiNes" is ready and working :

Also, I'm a big RGB video quality fan, so my nes has been modded to output RGB, replacing the original video processor, that output composite, with a RGB ppu processor took on a playchoice 10 arcade system. I don't have pics of the mod (a friend of mine did the mod, thanks to him ;D), but I can explain with schematics the procedure if you want.
RGB quality is godness, and with the famicom port, I'm able to play famicom disk system in RGB quality :star:

Oh my...that is so Godly!! I love this! The best of both worlds + RGB! Brilliant!
Nice!! Now you just need the ENIO or something so you can use Famicom keyboard and other things that uses the Famicom expansion port.
Very nice, just need to put a dust flap over the cart port and EXP access like P mentioned.
Fantastic :star: :star: :star:
Brilliant work, love it!

I recommend removing the sticker left overs and adding a famicom dust flap.
I'll remove the sticker ;D. I have a snes dust flap ready to install. Also, I have to do the extra sound mod for famicom/fds games. It requires to link two points on the expansion port.
Why not just get an ENIO to do that and give you EXP port access?
Going to check and learn about the Enio. I didn't know the existence of that until the last past days.

If he went through the trouble of adding a Famicom cart port, I think it'd be fairly trivial by comparison to add both an expansion port and external audio internally.
must...have... :o

APPROVED :)
Looks solid as rock.
My only concern is the NES Joint Converter - I remember those being extremely tight whenever I used one for FC games.
It isn't a hassle to remove games is it?
I have recut very slightly the converter, so famicom games are easy ti fit and to remove.
How hard was it to source the RGB PPU?
A friend found a stock of playchoice 10 in an arcade shop in France. Luckily a few had the PPU in place.
I'd love to get ahold of one one of these days.
I might just try my hand at this next time I'm back home and have access to tools and a shop to work in. Minus the RGB, of course.
So what did you do with all the wiring once you got the converter all assembled? I might be interested in tackling this myself.
You mean you want the pins' locations where to solder ? Sorry, I don't really understand the question :-[
Je crois qu'il te demande comment tu as disposé les câbles dans la NES après avoir tout construit (enfin installé)

C'est ce que je me suis dit, mais je n'étais pas sûr^^. Je réponds de toute façon. Merci de m'avoir éclairé ;).

@ 2A03 : The wires were flexible enough so I could bend over them, so they fit well in the empty space of the NES. Maybe when I got the time I will shorten them, but actually they fit well.
cool your idea is like mine :) ! great ;D
How about a 15 pin Famicom Slot on the side for 3rd party Famicom Controllers
Great job! My most sincerely congratulations! That looks really cool.
Matias : thanks^^.
MarioMania : I don't know if that would work. I often see nes pads on famicom, but not famicom pads on nes.
If that would work, it would be interesting to know if my famicom 3D system could work on my nes.

It's possible, all the lines you need are on the NES expansion port so all you should need are some wires.
You're right, and I forgot the existence of the enio expansion, with it I an use famicom periphericals on the nes^^.
I figure Famicom Gun Games requier Famicom Gun, Might not work on the Zapper
Nope. The Zapper works for all Famicom games.
Wow, Really..how so??
Like Famicom Duck Hunt on a NES..Works with the NES Zapper & the Famicom Light gun
It's the same device just in a different shell with a different connector.
Are there any new photos of the outcome?
Today I received a Enio EXP Board (thanks again Pete).
It works perfectly, I'm now able to use the famicom 3D system (and other famicom accessories) on my "RGB FamiNes" ;D.

Very cool! Glad to see you're able to use the 3D system. I'd never actually seen one before.

Awesome.

How much for the Mod in USD?
