Overview: PPSSPP is still in its early stages and thus very few games are currently playable. However, this will change over time!
PPSSPP should work on all modern Android devices. It's been confirmed to run on the following:
Nexus One (the slow GPU will probably be a problem later)
Ainol Novo7 Advanced II
