I tried a few roms that I had stored in my computer, the result of each game was the following:
-MegaMan Powered Up works perfectly
-FIFA 14 goes black after the auto-save warning, but the console does not freeze, until you try to exit to the menu when it freezes
-Peggle rarely starts, usually freezes when you start, or when the game has to load the pegs, it's a little demanding game
-Burnout Paradise starts well, but freezes after a few seconds, also presents some lag
-Def Jam Fight For NY The Takeover gives error message, but pressing any key returns to the Homebrew Launcher, does not crash the console
-DISSIDIA Final Fantasy works perfectly, although sometimes it may show an error before starting a battle, or crashing during a battle
NOTE: The configurations were not modified, the ones that come by default were used, games were tested in the first build
During these days I will be testing more roms as possible and I will comment here the results
