Anyone ever repro a FKROM (MMC4) game?

Guntz

I have a Fire Emblem Gaiden I want to convert into English, but I can't find any info on repro-ing a MMC4 game. I figure it's the same as MMC3, but there's no guarantee of that. Here's TKROM / TSROM for reference:

TKROM & TSROM:
PRG socket:
Bend up pins 1, 2, 24, 30 and 31 (or cut tracks 2, 24, 30 and 31)
Solder pin 2 to hole 24 (A16)
Solder pin 24 to GND (OE)
Solder pin 30 to hole 1 (A17)
Solder pin 31 to hole 2 (A18)
CHR socket:
Bend up pins 1, 2, 22, 24, 30, 31 (or cut tracks 2, 22, 24 and 30)
Solder pin 2 to hole 24 (A16)
Solder pin 22 to hole 31 (CE or CHR /A13)
Solder pin 24 to hole 2 (OE or CHR /RD)
Solder pin 30 to hole 1 (A17)

Can that be applied to a FKROM game and have the EPROM work? Thanks!

Yes, the ROMs in MMC4 games have the same pinout as in MMC3 games. Nintendo used the same ROM-pinout for all of their boards up until MMC5.

Excellent, thanks! Now to just get the cartridge open...

Assuming you are opening a Famicom cart, go to Youtube and type "How to safely open Famicom cartridges" thats the method I use it's pretty effective.

I went to a hardware store and actually found a set of vice grips like in the video, with plastic grips and everything. Time to open some Famicom carts... And maybe get some more.

Thats the method I used and it works well but be prepared to have it take a few tries to get the clamps just right. Took me a few tries any ways.

I did a clamp-and-pop on a Crisis Force cart. Not so bad if you take it slow. Had to squeeze the board out carefully to preserve the label though. That was more fun!

I'd like to follow up on this thread by saying I was successful in converting a FE Gaiden cart into English. Thanks again everyone! No broken tabs either.
