I always grab from the repository, not from Google Play.anyone do any PPSSPP testing?
The current version (v0.9++) has a menu that can be navigated by the Ouya controller. This control scheme doesn't translate to in-game unfortunately, so you'll still have to set up an in-game control scheme first before trying to run a game proper. With the new controller-supporting UI tho, its a cinch compared to when I had to use the touchpad.
The only key that isn't recognized is the Ouya key. (Comes up as Native+.??). The rest seem to use the iCade format, with ABXY for OUYA.
There's no way to get back into the main menu after loading the game, because the Ouya has no back button. The mapping was recently put back in, I gotta test that...
Don't turn multithread on, it flickers. (I also doubt its stability on anything above 2 cores. Multithread didn't crash on my S2, but FCs at unpredictable parts of any game on the Ouya. The Ouya's much faster than the S2 tho, so I doubt it needs multithread enabled.)
