No, they're not in the defender layout. I kind of sacrificed defender for this cab. I can only do so much with those little panels. 3 is enough to swap.
The way I arranged the buttons was for ergonomic hand placement, the two on the left hand side are for games like asteroids, or classic one or two button games, should the player want to use their other hand for the joystick.
I should have mentioned that this setup is strictly for old-school, classic games, with the exception of Golden Tee, and not for fighters...
