I have been using fpse on my non-rooted Nexus 10 for several months now. All my ROMs work perfectly.
Just recently I purchased an OUYA, love it! I purchased fpse for it but found that ROMs which work on my Nexus 10 don't work on my OUYA.
Not sure what info I would need to give you. The bios file I'm using reads 'schp1001.bin'
The two ROMs currently in question are Bushido Blade and Medal of Honor (two of my favorites). I saw a video on YouTube of someone using fpse on their OUYA and playing Medal of Honor, so I assume I must be doing something wrong.
Any help would be greatly appreciated.
