I made some custom BRSTM files for Project+, downloaded music, used Audacity to make it just right, made it a wav, opened Brawlbox, made it a BRSTM, and replaced a song. I used the boss theme from Wario Master Of Disguise over Battle With Wario, and a remix over Battle With Wario_b, then the remix played for 15-ish seconds before playing a bit of Bowser's Galaxy Generator sped up. What gives?
