This release of Daedalus for the PSP is currently in the very early stages of development. It is intended to show the potential for a N64 emulator on the PSP, but the current release has many missing features that make it far from usable:

 

* Not all the N64 controls can be used simultaneously.
* Many roms won't boot. 
* Many roms have serious graphical glitches. 
* Many roms have random lockups and crashes. 
* Many roms run at a low framerate.

 

Having said all that, I believe most of these problems can be overcome in the future.
