Parabolee posted this news he had found out about the Amiga emulator for the PSP:
Yes it is in development and we should see an update in the next week or two. Christophe Thibault (the guy working on it) posted on his board that he would be away till August 15th but will be working on it then and had some good idea's to increase the speed.
Right now it's cool to see running but the framerate renders it pretty useless (frameskip of 8!).
