hi i am a student and yesterday my tutor was telling me how the ds can be modded to fit a sony memory stick(same as the psp) and have a psp emulator put onto it. but he wouldnt tell me how to do this. does anybody know how i can find this out. my brother has a psp but i dont realy like them. but if i could get a ds with the capablitie of playing psp games then i would purchase a ds this afternoon.please help as much as you can?
