The Undamned InfiniKey-CPS2 is the ultimate battery replacement solution for CPS2 arcade boards, designed by UD Game Tech - the trusted name behind legendary consolized CPS2 systems and USB decoders that shaped the tournament scene.
CPS2 systems use an encrypted architecture with a battery-powered RAM chip that holds the decryption key. When that notorious "suicide battery" dies, your board becomes a paperweight. The InfiniKey-CPS2 completely eliminates this problem by replacing the battery system with a permanent solution.
Installation requires basic soldering skills. Remove the original battery, identify your ROM chips, match them to the included reference chart, then bridge the corresponding Game Select pads. The InfiniKey automatically loads the correct decryption table for your game.
Whether you're building a MAME cabinet, restoring original CPS2 boards, or running tournaments on authentic hardware, the InfiniKey-CPS2 ensures your games stay playable for decades. Tournament organizers especially appreciate the reliability and peace of mind.
