On WPC-89 and WPC-95 games, when using an EPROM that is larger than the ROM file for the game or sound ROMs, does the ROM image need to be "doubled up" like on older game systems?
For example, if I have a 128KB file and have a 1MB 27c080 EPROM, would I just burn the 128KB ROM file as-is, or would it have to be doubled up 8 times to fill the whole EPROM?
