My brother had an XPERIA Play, until about a week ago when he got the Galaxy S3. I have an HTC One X, so I want to use this Xperia as a gaming device, but the performance on a lot of games is excruciatingly slow. I want to know if I can flash a ROM on the Xperia Play 4G, just for games and nothing else. Something like GinToJB or similar.
