Some awesome news for the WiiU Scene, the PSP Emulator PPSSPP has been ported:

The Wii U homebrew scene is still alive, proven by a new emulator for use on the Wii U: PPSSPP. The gameplay is choppy for most games that have been tested, Ridge Racer and Street Fighter Alpha 3 among them, but this emulator's release is an alpha build, meaning there's certainly more to come and refining to be done eventually. This adds yet another system to the Wii U's emulation repertoire.
