I really wondered what the song required more ARAM than the SNES usually has multiple times. But then again, the issue is like most echo buffer issues: Reduce the echo buffer. Ramon's post explained it pretty well:
Originally posted by Ramona) Reduce the echo's delay (first value after a $F1 command, usually somewhere at the start of a song). This is the recommended fix. AFAIK originals never exceed $04 or so, but in my experience values up to $0C are safe to use with default global songs
For that matter, that's
That's the $FD in "$F1 $FD $63 $01"
