Daedalus is an established open-source Nintendo 64 emulator for Windows and the Sony PSP.
As this project hasn't been touched for some time, some of us have gotten together and started work on reviving this little community mostly focusing on the PSP to start with and then moving to other platforms!!
We are now at https://github.com/z2442/daedalus
