Retrozone's PowerPak

[satoshi_matrix]

Okay. Which "side" of the 72-60 pin adapter do I mount the resistor to, the front (facing the power switch and controller ports) or the back (facing the power and video connections)

I'm guessing it's the front. I've put links to high res pics of my adapter. can someone please indicate exactly where to solder the resistor? Thanks.

I had the expansion sound working perfectly for months, but when I upgraded the boot rom on the powerpak to 1.11, it stopped working. I replaced the resistor and tried everything, but I can't get it working again. has anyone else had this problem or know how to fix it? any help would be greatly appreciated.

I bet you could send it back to retrozone and have them fix it. only thing it should cost you is to ship it, and if you live in the continental us that really shoulnd't be much.

I'm still looking if anyone knows how I can add fds expansion audio via the powerpak into a cartridge connector for my AV Famicom. Thanks.

Gimme some time and I'll get you the relevant info about which pins you need to tap on to get enhanced audio.

Do you guys know if Kirby's Adventure works? Does Little Nemo: The Dream Master still have graphical glitches?

Thanks.

Kirby's Adventure does work.  I haven't tried the other game though.  I would, but I don't have access to my PowerPak right now.  I'll let you know sometime during the week if someone else doesn't get to it first.

Hey! I found a guy on nes dev that has figured out how to get the PowerPak to produce FDS expansion audio and successfully transfer it through an NES to Famicom 72-60 pin connector to any Famicom, just like what I want to do.

He says to cut the bridge between pins 45 and 46 on the Famicom input and solder a 10k resistor between them. After that, you solder another 10k resistor from (I'm assuming?) Famicom pin 45 to NES pin 54.

He's also got a blurry video up on youtube. Here's the link. http://www.youtube.com/watch?v=WsfUviciKxs

I'm not nearly as technically inclinded as many, and I post this to ask for help in understanding the subject matter.

Really, here's just my logical (?) understanding of what to do.

I know there are a total of 60 Famicom pins and 72 NES pins, meaning there are 30 Famicom and 36 NES pins per side of the NES to Famicom adapter. If Famicom pin 1 is on the "front" of my adapter, pin 45 and 46 is on the "back".

Since Famicom Pins 45 and 46 are the only pins that are connected together and they are on the "back" of my adapter, I know that Pin 1-30 must be on the opposite side, the "front".

I also know to play NES games on the Famicom, you always have to put the games in backwards with the labels facing away from the front of the console. Based on that, am I correct in assuming that NES pins 1-36 are on the "back" of my adapter, which is the reverse side of where Famicom pins 1-30 are located?

If that's true, then pins 37-72 are on the "front" of my adapter along with Famicom pins 1-30. He says to solder a 10k resistor between pins FC 45 and NES 54. Since those pins are psychically on opposite sides of the adapter, once again am I correct when assuming I can place that resistor in between the closest via to pin 54?


Thanks as always!

I was able to solve the problem on my own. I'll make a blogpost on it for others who might want to do the same mod.

Sounds interesting, but I'm not gonna put solder on my powerpak in a hurry for a couple extra bleeps here and there.

You wouldn't be touching your PowerPak at all. You'd be modding the 72-60 pin converter or your NES console.

For the record, Little Nemo and Kirby's Adventure both work perfectly on the PowerPak now.
