Super Mario Bros.: The Minus World

(MODERATOR NOTE: This hack should be played in ZSNES to avoid music glitches.)

After the cancellation of my first project, SMW: Remix, I have made a newer, better, and much more fun hack! This is Demo 0.1, and contains World 1.

fixme: custom music glitch causes crash in accurate emulators. Some ASM also does not work in the latest ZSNES. A specific outdated version of an emulator is needed to play hack as-is, which is ZSNES 1.42.
