Okay, I don't know much about PSPs so please bear with me.
Is there such a thing as a PSP emulator yet? I don't think there would be due to it being a next gen handhold and all. But if so, can it play commercial ROMs?
Failing the above, can you play ROMs on a PSP. I've heard you might be able to but only with a certain version. Can PSP's versions be changed if this in-fact the case?
And what is the availability of commercial ROMs, i.e. downloads, torrents etc?
And what sort of sizes are they?
Help is greatly appreciated, thanks.
