I hope it's alright I make a new thread for this. If it should've been elsewhere (I dunno, a Mega Collection help thread or something perhaps), sorry about this.

Anywho, I was just reminiscing of blissful days playing Sonic 2 and remembered this one time I managed to - somehow - speed up the music tracks in Sound Test so it was like I'd collected the speed shoes item box. Every music track I played from then on played in sped-up form - even things like the title screen music. It must have been activated by the order I played certain tracks/sounds (ala activating level select, debug, instant all emeralds, etc), but I haven't ever been able to replicate it, and haven't seen it on any Sonic 2 codes page online.

Has anyone else discovered this and perhaps know how to activate it on purpose? When I did it, it was a total fluke coincidence and I'd really like to know how exactly I did manage it so I can hear all the tracks in hi speed again
