playing PSP games on a machine that actually had 2 analog sticks would make me hurl the damn thing out the window
the one PSP game, Monster Hunter 3rd Portable Freedom G whatever, uses the right analog stick for camera.
It isn't explicitly said if this is a feature of the emulator* or a special version of Monster Hunter. By my eye, it seemed like the camera movement was very digital, and since the d-pad was still mapped the camera, I believe it was just the d-pad mapped to the second stick. I'm optimistic that it is a feature of the emulator, similar to how remote joy works.
It work for every game, but if that is the case, it would be pretty nice to just fiddle with button mappings to get games playing relatively smooth. Syphon Filter has an option for analog aiming and moving with the face buttons. Map face buttons to left stick and left analog to right analog, it should work well.
*on that, they mention that PSP games are emulated. They didn't go to deep into it, other than showing the Monster Hunter demo and saying the games do look better on the NGP.
and yes, I really hope Sony has a way for us UMD people to get games on the NGP. Won't happen, but it would be nice! I only have like five or six games on PSN that were either free or download only (like Thexder Neo)
just a random side thing because people are talking about 3DS in here to: I wonder how DS games on the 3DS will be. Surprised that they haven't shown them off at all. I hope it isn't like GBA on DS where they map the resolution 1:1 and you have large black bars around the picture.
