It looks gorgeous! Very nice port indeed. The limitation of games though, snes9x should work with every ROM out there so what's that about? Also regarding speed, I don't know about the current version but older versions ran fine on a CSPPC and on my XE. SNES9x also runs at full speed on my Samsung Galaxy SIII, although that CPU is faster than the G4 in my XE.
I tried it with the Retro Design joystick adapter and a CD32-pad which I thought would be perfect for SNES emulation but only some buttons worked and I don't know if you can configure it somehow? I only tried it quickly with Super Mario World.
