Hi
im new to retro arch scene, i normaly use mame for my roms but a friend said to give retro arch ago. Ive just done basic setup of my control pad and i can play some of my roms via gamepad fine.
So my question is ive got an aimtrak light gun plugged into my pc all configured in windows and works fine in mame. retroarch detects the light gun at startup but says its not calibrated .
where do i go to calibrate gun ,im finding the retro arch GUI abit confusing. is thier any guides to help me get it setup for retroarch and mame advance/ mame cores.
