The main difference is, I think, more voice acting and different combat special effects. I hate to say this but I like the hand-drawn ones better than the PSP-animated ones. The US audience for this game is definitely those that missed out buying on the GBA, because the game seems otherwise identical.
I wanna say it was a typo for the fun of it, but the 'L' and 'R' keys are kinda apart from each other so...meh...
Still, the trailer did get me pumped up for the game...again...
