Hey bro, this is my first post in like years.
Anyway, it shouldn't be hard to make a cp overlay for the x-arcade. It's the same as making an overlay to any other stick. Just measure the stick and make some art. You can either lay it on top and put plexi over it or you can just laminate the art and super glue it to the top. I would prefer doing the lamination on an already completed stick because with the plexi you will have to re-measure for holes in the plexi then cut those and if you're off when you're cutting then the plexi will be uneven. Also, the height/ thickness of the plexi might conflict with the joystick, it will become shorter. Thanx.
-See Ya!!!
