i lost all my gaming systems in a house fire over a year ago, ive since picked up another dreamcast and games are easily found in here, when i download a game and unzip it and then burn it will not play says "please insert a game disc" ive used alcohol120% img burn and nero, when i unrar it remains a rar file and i cant seem to figure out if it should be cdi or a bin file......i also have used power iso
