The PSP emulator was having similar problems to the other emulators listed in that I couldn't get the analog sticck working. I think also that the dpad may not have been working properly either.
I tried several of the N64 emulators available. All of them were very slow and jerky. The emulators were:
mupen64plus2rice(may not be the exact right name)
There were other emulators but they were all variants of the mupen64plus name.
I tried using the esc key to access the configuration and binding settings but all it did when pressing the keyboard was to exit the game back to the game selection screen.
I found freeintv and that works much better than the other intellivision emulator.
