Sorry about the lacking details, I'm a bit tired.
I will have 2 player set up, with 6 buttons and a joystick each. It will also have a p1 and p2 start button on the top. Other controls will be located elsewhere.
This is where I'd like advice/suggestions. I am very new to this so I don't really know what seems like a reasonable idea. I considered plugging and covering the excess holes with wood and then sanding/repainting the CP, but I don't know if it is worth it. I personally don't have access to many tools, but I have a couple friends with some, so I also considered remaking the top.
It could use the same layout (and if I make a new top, it probably will) for some of the button and joystick holes.
The joystick mounts don't match up, so new ones would be necessary.
Thanks!
