I run a Jrok board in my Joust, Bubbles, and Sinistar. I have the original boards all wrapped up in the cabinets so they can go back to original. I got tired of always getting them repaired and working on them. I have them all to boot to the specific game, way more reliable.
I am still running original boards in my Defender and Robotron though and never had any issues with them.
