I agree with you Mooky, I don't understand why sony fights homebrew, I guess they don't want every advantage they can get....
They really should embrace it, maybe not market it as a system that can run homebrew, but leave it so people can if they want to. I think that the PSP would be more of a powerhouse if they let it be and focused on MAKING ORGINAL AND GOOD GAMES for it.
I guess they would rather block people from playing genesis games, so they can emulate them and sell them on UMD for 20 bones. That whole 14 copies they sell will really turn the tide on the DS.
