There are two options: either you can "force" the ROM to be detected as a ROM with supported mapper (in that case, there are like 7 working mappers, so I should make 7 different CIAs) or you can wait till I release the New Injector, in which I'll add the option to make forwarders for those games that aren't working by the injection.
My injector detects the mapper of the ROM and it looks if it's compatible or not. In this case, there isn't.
