Long Answer: Kinda. SofiyaCat (Creator of PSPTube) ported DeSmuME to PSP, which was then slightly modified by Sektor. You can only put one NDS ROM on your MemStick at a time, and the emulator has very low compatibility with commercial ROMs. The games it will run, however, still won't play over 3.5 fps.
