Death Race should be like all other Color Dreams/Bunch Games/Wisdom Tree releases and be assigned mapper 11. However it doesn't work with that mapper in emulators. Any emulator that allows it to work uses a custom mapper. Kevtris's says that the only difference bewteen the board used for this game and the board used for all other Color Dreams/Bunch Games/Wisdom Tree games has to do with bus conflicts. Is this significant of an unimplemented mapper feature?

Mapper 11 seems to be a really wierd one.

I got a NES ROM image that is mapper 11, and works in all emulators. But no matter what donor board I use (that is a mapper 11) the game is all messed up.

Describes the slightly unique board that Death Race uses.

Yeah, Death Race relies on the 'feature' that dataline 0 on the ROM always wins when writing to the mapper. It boots fine here after implementing that just now (thanks for the link)... something like: written_data|=(read_rom(address)&1);
