I have no idea what is going on in here, but 99,9 % of all PS3 games display absolutely nothing in rpcs3. The 0,01 % that do display something are games with primitive graphics, and they do so at absolutely unplayable frame rates. If you wan't to play MGS4 get a real PS3 or wait several years for rpcs3 to maybe improve. End of story, go home people.
