I am building a CP for a 24 inch wide cabinet (originally a Sega Gremlin Championship Baseball) and would like to have:
- Two 8 way joysticks, each with three buttons
- one trackball
- one 4 way joystick
- one 2 way tank stick
This layout has buttons to the left of the sticks:

Is this a good design? Should the buttons be to the left or right for right handed people? I put the tank stick and 4 way behind the buttons so that the joysticks would not block each other. I figure when using the tank stick the only button needed is the one on the top of the stick, and when using the 4 way for galaga the only button needed is the player 1 number 1, so everything is accessible.
I only have three buttons because I do not expect to play any of the 4 or more button games. Game play is generally Metal Slug, Ms Pac Man, Galaga, Centipede, Battle Zone.
Sorry if the image looks bad when it gets shrunk, if you right-click and view image it looks better.
Thanks for any feedback,
Dan
