I think that's an unfair statement to say there are no good emulators for the IT. I don't use them, but both VGBA and iNES are both in the Maemo Download - and most software in that repository are of good quality. In addition, there is DOSBOX (for DOS games), a MAC emulator and even a commodore emulator out there. I'm sure their are more in various states of development. I think if you do a bit more searching, you'll find emulators well support on the ITs
