lol yeah, but playing Super Mario World with PlayStation brand buttons (triangle, square, X, circle) is just wrooooooong XD. Hopefully the 3DS will get hacked someday...It's great to have the capability on the DS, and I'm glad SNEmulDS is still being worked on, but if you were serious about having the emulation in your pocket, you would have bought another device for it sometime before now.
Also the PSP screen is 480x272, while the 3DS screen is 400x240, so SNES games would look better on a 3DS anyway. I don't have a PSP, so I wouldn't know if the SNES emulator on PSP has scaling or not, but scaling always looks really dumb, except if it's on a television. The DS only has 256x192, so while the width matches most SNES games (which is 256x224), the regular DS screen is smaller so you'll get things cut off which is just laaaame.
