Just curious, it's been awhile since I've used the Ouya. I have it paired with my PS3 controller fine and want to only use it as an emulation box. I know there's no more system updates but am I able to update Android at all? Also, if not what are the latest versions of the following that I can install?

Mame4droid
RetroArch
GenPlusDroid
Something for CPS2 games
