A $140 PSP-3000 is nice but sadly you can't hack the motherboard for those yet. Even if you obtain the games legally, the lack of homebrew is a bit of a drag. I can use NES, SNES and Genesis emus on my DS but they are not that good. NES/SNES/Genesis emus are no where near as good on DS as they are on PC. PSP emus on the other hand are quite comparable in quality to the ones on PC when it comes to NES, SNES, Genesis, Sega CD, PS1 emulation, etc.
