thanks for that, i had to set raspbian to boot into console mode though and not the desktop.
question - i tried out playstation and as soon as i clicked that, it went to a black console screen, then reloaded piplay in a different resolution, but went back to the main pi play screen. i then clicked playstation again and it just kept looping back into piplay without giving me an option to choose rom.
i then tried SNES and loaded a game - mario brothers 1/2/3 combo it allowed me to select the game, but graphics went all crazy and unplayable. any ideas? im 100% new to piplay thanks.
