Does this synth support Yamaha XG instructions And/or GM2?
If not, is it possible for you to add it?

I know at least one Soundfont that attempts to cover XG instuments (Giant Soundfont, to be specific), and it shouldn't be too hard to support GM2.

Apparently,  drums are not changing to the XG compatible bank when playing a XG/GS song with the Giant Soundfont.

Also, it's as if this synth ignores the bank switch feature. (examples: http://www.vgmusic.com/music/console/nintendo/gameboy/gsbattlexg.mid/ and http://www.vgmusic.com/music/console/nintendo/snes/smwbow.mid, the former, the Square Lead instruments are supposed to sound unique, and the latter, the "waves of the sea" sound's supposed to be thunderclaps {and I doubt that the latter's XG music}).
