Doh only uses one button, the same as Arkanoid.
If your cab is wired for Jamma and has an Arkanoid to Jamma adaptor then you can plug the Doh board into the cab and it should play fine. If your cab is wired for Arkanoid then you will need an Arkanoid to Doh adaptor. I am actually in the process of building one of these for someone else right now.
