The Simpsons Game psp/ds unlocking?

Does anyone know if I can unlock the above game,in order to open up each chapter-so my son can access everything.

There doesn't seem to be any normal cheats that do this, have you checked to see if the DS version has any AR codes that unlock it?

There are cheat apps for psp, that cheatup app, but I have not used it before...One option (the one I alway do) is to just beat the game and let him replay where he wants.
