Are you serious?

I figure that's alot of Kontent to put on that little Umd disc. I could imagine the MK team pulling out their hair from trying to make MKA for Psp.
Take it from me. Just buy a 8GB memory stick, and use the Psp for it's multi-media purposes kid.

*Music, photos, not so much the games, and a nice wide screen to watch hours of movies/shows on the go.

Or do what I do and use Homebrew so it plays N64, PSX, NES and games for anything else before the PS2 came out.

It's safe to say everyone is telling you that there is no realistic way to get MKA to play on a PSP and that it would be impossible to get that much content into a PSP game.
