Famicom english conversions

The nes powerpak doesn't reproduce custom audio chips found in famicom carts like the real thing. I can play the same game using the powerpak and the real cart and I can hear the difference. Also the nes powerpak doesn't run mmc5 games at all (like just breed). Therefore I set out to convert the actual carts to english (or as many of them as I can). Here's the lineup so far:









Many thanks to the great people of Romhacking.net for making these awesome fanslations. Madara and esper dream 2 were fairly straightforward conversions, the maskroms on these pcbs are 100% eprom wiring. All I needed to do was burn the eproms and solder them straight into the boards.

Just breed was one difficult game to do. The rom by default uses color emphasis bits which makes it not run on a rgb ppu chip. Thanks to thefox and dwedit on nesdev we patched the rom to run fine on a rgb ppu chip (and of course it'll run fine on a stock composite ppu chip too). The wiring in a mmc5 cart is custom so a lot of rewiring was needed:



As you can see I also installed holders for the save batteries for easy swapping. This's all part of the same project group as my gimmick famicom conversion with the 5b audio:

Neat. Where did you get those save holders? ive been trying to find some forever but every one i find, the cart wont close back up with it installed.

ive been using soldered in batteries again wich i dont want to do.

Sofar the only save holders ive found are for the rechargeable battery in the dreamcast. my two dreamcasts have them.

Got the battery holders from ebay. Designed for the cr2032 battery

ill take a look again, for this particular one. i Tried several 2-pin sockets that fit except that they were too tall and the cart case wouldnt close.

but the one i see is surface mount. are yours surface mount or through hole?

Uhm, I can't remember honestly.

Mvsfan, ebay item 140396427505 from wonderco_buy are perfect. They are smd but the pins can easily be bent to fit on the pcb. I've changed many batteries and I'd recommend buying them from him =)

DO you guys know if someone is working on a Lagrange point Translation? This game really needs an english version.

Gidion Zhi has the game translated but he's unable to fit the english script. The lagrange point game rom is highly compressed since the vrc7 only supports up to 512k roms. Gidion refuses to release a translation that removes text to make it fit, however due to the hardware constraints I don't see how else it could be done.

Sounds like an annoying situation...

Yeah the vrc7 really makes me scratch my head. What's also strange is lagrange point has the chr data and prg data compressed into a single rom. When you fire up the cart it decompresses the chr data into the onboard ram chip which is why there's a pause before the game runs after you turn it on.
