When buying FPSeCe through the OUYA store, does it have some kind of DRM? Does it try to activate itself somehow? Does it check this status everytime I start it? Am I able to use it offline for unlimited time?

The gamepad action buttons (O, U, Y, A) on my OUYA gamepad controller do not work in some games. I can't stop the intro sequences, and can't select anything in the main menu that shows after the intro finished. The buttons work in other games, so I presume it's a game-specific problem. At least this...

I'm using FpseCE on the OUYA. When trying to re-configure the gamepad button mappings, I can configure the first button just fine. After configuring the first button, I'm somehow in a second button mapping window that gets closed when I press "back". Then I'm in the original button mapping...

I'm using FpseCE on the OUYA. When starting another game, or even a game I previously played, the gamepad button mappings are lost and I have to re-configure it.

Is this a known problem?
What can I do to fix it?

I'm using FpseCE on the OUYA. In every of the 10 games I tried, sound stops after about 1 minute.

Is this a known problem?
What can I do to solve it?
