This is the Daedalus R12 Nintendo 64 Emulator plus 24 working roms for use on the PSP. Also included is a long list of roms that I have tested and a short description of how they run. This requires 1.5 firmware or the ability to run 1.5 homebrew.
To install on 1.5 firmware unzip the file and drop the Daedalus and Daedalus% folders into your PSP/GAME/ folder. If you have OE firmwares, drop the Daedalus and Daedalus% folders into your PSP/GAME150/ folder. If you have an official sony firmware above 1.5, your PSP is not capable of running the Daedalus emulator.
