This thread is somewhat misleading for instance there is no Dreamcast or Gamecube Emulator for OUYA even if it powerful enough to run them.

I doubt You will see any vast improvements in PSX N64 emulation except some OUYA specific optimization, simply put if there was to be any improvements it would be the PC versions first that are years and years old, then you can go down ladder from there.

No one really make emu's from scratch anymore, rather they just port over pre existing emu's to work with whatever system, every once in a while you will get someone to improve it for that system if the performance totally blows.

What would be a nice touch (Don't know if this something currently available on any emu) is if emu devs somehow could start putting profiles into them, like a configuration file that would automatically adjust an emulators settings to the best know settings for any certain game when it is loaded.
