Does anyone know where i can get a SNESor a GBAemu for the psp? And how to use it?

I've been trying to figure this out for ages now but i can't.

If anyone can help me - thanks.

Check the downloads section listed above.

Also There are multiple other sites that host copies of the emulators for the PSP - most also have instructions on how to install and set up. Try psp-hacks or DCEmu - you can google search for the addresses.
