sonic classic

I have an Acekard 2 and running version 1.5.1. When I try to play sonic classic, i pick the language, then get a message that says save failed, turn off
the game. I downloaded version 1.6, but after I choose a game, all I get is a white screen. Any suggestions?

I'm pretty sure it works on 1.6RC2.Download 1.6 RC2, backup your games/saves, format your microSD, and put everything on it (including the new firmware).
