We need a cheater

[IndianCheese]

The PSP desperately (well maybe not desperately) needs a homebrew program that hexes UMD games like GameShark used to do so we could stop pretending we enjoy UMD games and actually enjoy them. Have you noticed the lack of "up, down, down, O, O, X, L1, right, right" type cheats now a days?

I totally agree. I'm a cheater and that's all about it :P
