Important:

Why Upgrade?
Arcade1Up’s stock control boards often limit gameplay with unresponsive dials and trackballs. The GRS 12-in-1 Interface Board allows you to breathe new life into your cabinet by converting your controls to USB — perfect for connecting to a PC or emulation setup without replacing your entire control deck.

Easy Installation
Just connect your spinner and trackball to the GRS board, plug in with a Micro USB to USB cable, and you're ready to go. No mods, no mess — just better gameplay for titles like Tempest, Missile Command, Major Havoc, and more.
