Famicom Mini - Vol. 01 - Super Mario Bros. (J) (V1.1).gba

Play unused Game Over variation everywhere (due to a Game Boy Advance emulator bug, the "shrinking" sound effect would at the beginning of the song. Without knowing exactly why the emulator causes these problems fixing the issue wouldn't be easy to fix, and would require a stupid amount of code changes where it would be impractical for emulators without needing a patch. I really don't feel like spending the effort. Lots of emulation issues with the NES emulator version. I'm not going to rewrite the emulator for obvious reasons. The codes were not a direct conversion from my original NES code because the rom itself was changed around in the GBA port for some unknown reason. The emulator that was developed is not very accurate.)
