Track Music Expander [CLF78]

[CLF78]

This code lets you apply different music for each track (including Nintendo tracks) on CT-CODE and LE-CODE based distributions. Simply place two BRSTMs named SLOT.brstm and SLOT_F.brstm (where SLOT is the track slot in hex) in the "strm" folder. If the file cannot be found, the game will fall back to the original music file(s).
