* Force save type for UNFLoader This fixes save type not being autodetected on SC64 with EEP4K due to the non-ED cartridge ID. Changing from SM to ED is a last resort, as emulators or other flashcarts have no means of autodetecting whether a ROM is an SM64 hack otherwise. * Rely on ED header for UNFLoader autodetection of save type instead
