Until a couple of months ago we had nothin but some compatibility but no sound. Be honest you whiners out there, the first time you booted up Mario and heard "Its me, MARIO" you heart didn't skip a beat.
Give people time and patience. The authors got $2000 for exactly what they were supposed to get it for and thankfully they deceided to invest a percentage of that money into improving compatibility/quality of their emulator. Be patient and stop biatchin
