Making a MMC5 repro (Just Breed)

I own a bunch of worthless MMC5 games... I even own several copies of Just Breed somehow. I don't have a EPROM burner myself but I have a couple friends who own them, and would let me borrow it to make my repro. I want to take one of my MMC5 carts and put the translation of Just Breed on it. The only thing stopping me from doing so is that I have no idea what kind of chip I should buy in order to make a Famicom/NES repro. Has anyone done these, if so, what chips should I be looking to purchase? Thanks!

 

I believe you can use 27C256 or 27C512 but I dont know to much about the repro thing.

 

here is just breed info: http://bootgod.dyndns.org:7777/profile.php?id=1409

you need a 512kbyte and a 256kbyte eprom , split the translation rom to PRG and CHR data, burn them to their respective eproms and solder them on the cart. You will NEED to rewire them though, info and tutorial here (it's the same for mmc5) http://callanbrown.com/index.php/advanced-mmc3-nes-reproduction

good luck!
