What I'm asking is whether or not it's possible to play PS2 games on the PSP because I have Kingdom Hearts 1 and 2 on the PS2 but my PS2 broke. It would be great to just have all the KH games available from my PSP so I was wondering what exactly is possible as far as playing PS2 games on the PSP.

I read somewhere that the PSP is as powerful as the PS2, so my hope is that it's possible.
