MVS bootleg roms change?

[pubjoe]

Hi,

I've received an MVS cart that turned out to be a boot, and seeing as these bootleg PCBs must have been in production I was wondering if they were used for various games.

Is it possible (and practical) to change the EPROMs to convert it to something else?

It's a Neo Turf Masters btw.

Possible but probably not practical unless you have some experience converting games. All the MVS documentation out there is for converting actual pcbs. So for that bootleg pcb you’d be starting from scratch determining the rom sizes, pinouts, jumper configurations, and whatever addressing logic is onboard. The first thing I’d probably do is try to convert it right back into a Neo Turf Masters, but actually using all EPROMs instead of those several mask roms. That would involve solving some of those issues above, but would at least limit some of the variables.

Thanks.

Yeah that'd be me out then. I had this silly idea in my head that it could possibly be done with no knowledge.

For example maybe if I could somehow find rom data of another bootleg that uses the same boards.

it's probably very close to the original
the original uses PROGBK1 & CHA256

i can see similarity's
board2 is pretty much identical
board1 looks like they just used double-size roms
