quick gamepark xgp emulation question(s)

[galaxykidgamma]

i've been looking at the specs for the xgp mini (arm9 200mHz - expandable ram) and like, all i want it for is GBA and SNES emulation. What's the [processor] rule for a succesful emulator? I know GBA and SNES have a 16.8mHz and 3.something mHz processor respectively, so shouldn't the XGP be more than capable of succesful emulation?

also, the GPH console, GP2X... how is the snes/gba emulation on that? i heard maybe 60-90% SNES w/o sound. that's not good enough for me.

and finally, any word on dev support for the XGP/XGP mini?

thanks a whole hell of a heck of a mess of a lot
