openkey-cps1 / cps1.5 / kabuki (inifinikey)

Similar in function to the legendary Infinikey, from undamned/UD-Tech, the openkey-cps1 and openkey-kabuki enable a games decryption keys to be injected on boot without the need for a battery.

openkey-cps1 is an on-the-fly CPS-1 B-21 chip programmer that consists of a PCB that sits between CPS1/1.5 B and C boards. It only supports the following C-Boards: 90630C-4, 90631C-5 & 92641C-1.

openkey-kabuki is an on-the-fly Kabuki (QSound) CPU key programmer that consists of a PCB that sits between the CPU socket and the Kabuki CPU. The Kabuki CPU is found in Mitchell and CPS-1.5 arcade boards and contains keys for decrypting/decoding the program ROMs.

There is absolutely zero difference in game function between openkey-cps1 / openkey-kabuki and a live battery.

NOTE: The "openkey-cps1.5 (combo)" we offer in our store comes with both an openkey-cps1 and openkey-kabuki and has a special version of the openkey-cps1 without the header shroud above the pins. This allows a little more space for clearance when closing the cps-1.5 case; either version of the openkey-cps1 will fit in the case just fine, however we've opted to include this special version in our combo package for ease of installation.

openkey-cps1 and openkey-kabuki are both open source projects, it's author has kindly given us permission to make and sell these products on the site.
