Project Kajitsu?
Project Kajitsu (Kajitsu is Japanese for Berry) is the brain child of Mike Wolak and Jasen Hicks based on the $35 Raspberry Pi B+ Model. The goal was to use the Raspberry Pi with a custom Pi Hat / Linux kernel and turn 2 ordinary PS3 or XBOX360 controllers into 2 Discrete JAMMA compatible controllers. We succeeded.
