Super Mario Advance - Music Pitch Correction (Game Boy Advance) Romhack

In Super Mario Advance, all the music tracks that originally came from the SNES version of Super Mario Bros. 2 / USA (included in Super Mario All-Stars) were transposed to play a semitone higher.

Interestingly enough, inspecting the sequence data of the SMB2 music tracks reveals that they were actually programmed in their original pitch. However, the developers later included detune commands in each track to transpose the notes to another key, which is what you hear in the actual game.

This hack edits all instances of said commands so the SMB2 music tracks no longer have their notes transposed, allowing them to sound closer to their SNES renditions.
