Tip: Don't edit the 8x8 tile of the upper right hand corner of the sideways walking Koopa Troopa in GFX01 (unless you want your coin sparkles to look glitchy).
This is a very nice sounding and well made port, but there's a little problem with the AddmusicM version: since there's a bug in AMM that when you use a percussion instrument on an SFX channel (#4, #6 or #7), the sound effects will mess up (Mario spinning etc.). So, either move the percussion channel to another one or use SMW-like BRR samples to fix this problem.
