The snares are missing some panning as well as the @1 on channel 5 on the 31 second mark needs to be panned opposite. Other than that it's a pretty good unsampled rendition. I had to lower the volume down though bc sfx was barely audible during gameplay. Keep in mind music is in the bg in SMW and not in the "fg". That @0 needs a softer attack, try something $DA $A0. The lead also needs some vibrato.
