I'm tempted by a PSP ... but I'm wondering what all this downgrading malarky is all about.
I know that you can download home made games, like chess and things, for the PSP... and apparently they dont work with the PSP firmware over version 1.5 ..?
But I've also heard that certain commercial games won't work on a PSP with the 1.5 firmware? Is that true?
Can anyone fill me in on the benefits of having firmware better than v1.5? It's a bit of a stinge that if you buy an up to date psp you can't play home made games on it!
I can't find a decent PSP website that explains all that
Maybe someone here will know... 
If I get a psp, I wanna be able to play all commercial games, and home made ones
