This may sound dumb and may not work but

If anyone can write a SNES emulator for the GP2X device that can run Super Mario RPG and Kirbys Allstar 8 Games in 1 at full speed I will pay for it
if this goes aganist rules than it may get shut down.

O_O

Why hire someone to create the emulator when it's cheaper to buy the console? Maybe what you want is already possible. However, I think it is not allowed to speak about these kind of things on the Conitec forums.

get a PSP

Both the PSP and the GP2X cannot play the following games properly:

and I own a PSP, DSLite and a GP2X possible

but the DSLIte can... you just have to know how

and NO, i will not tell you!

Oh offcourse the DSLite is less powerful than both combined and it totaly can thank you for your insight.
