I have both. But to tell you the truth, I barely touch my PSP. I take my DS everywhere. There is just so many things that make the DS better. It focuses on games not on useless iPod-ish extras. Trauma Center rox!
I've been fighting Hitoshura at the end of my second playthrough. Kinda frusterating.:buh: I read all of the FAQs on the matter so I know the strategies that those people used. Anyone do anything different to beat him?
