GroovyMAME will display this box "Not Optimum Mode" that bounces around the screen when I launch the program, If I go back to the original MAME, it launches fine and games load... I have no clue what Ive done wrong.. Is there a way to set everything back to default with GroovyMAME? I was messing around with Arcade_OSD when this all started, before that GroovyMAME opened and I could load games. Samsung 19" WS monitor is being used for setting everything up before switching over to a 32 Toshiba TV.
HUGE thanks in advance!
