Does anyone here have any idea how to convert a copy of Tengai Makyou Zero (Far East of Eden Zero) cart to use the translated English rom?
I have an original TMZ donor cart, and the necessary tools to desolder the original mask rom, but apparently the translation patch expands the ROM size, so it's not as simple as just swapping out the old ROM chip. I know it's possible, there are people selling copies of the English translated cart on various places, but
1) They're charging $100
2) I don't want to BUY a repro, I would prefer to just convert my own FEoEZ cart (and this is something most translators are usually ok with).
The few tidbits of info I've found on other websites do include pictures of existing repro carts, but no other details, and they're too small/blurry to use as a guide. I'm assuming they use several address muxes or demuxes to deal with the change in ROM size, but I still don't fully understand how to integrate muxes/demuxes in a scenario like this order to figure out what kind of circuit I would need to build to this work correctly, so any information would be appreciated.
Ideally I'd like to build a translation PCB and post it somewhere like OSHpark or other locations so that other DIY-minded repro makers like myself don't have to pay exorbitant markup in order to play this game on original hardware in English.
Thanks!
