Thanks for the tips. I've already got the panel assembled, just need to start drilling holes for buttons, so going to stick with the 4'. It really doesn't look all that out of place with the wrap around I've got going, and I've got a 27" TV in there, so it should be ok. I will take your advise on the admin buttons. Can I ask you where you hid your tab button? Or what button you use for shift?
I dont think I'm going to go with a spinner. I don't ever recall even seeing one at an arcade! I started going to arcades in the late 80's early 90's so just about all my favorites are side scrollers like X-Men, TMNT, NBA Jam, etc. So I know it's a fought over subject here with the angled joysticks, but I think that is what will work best.
How wide is your trackball plate? I think maybe I will move the player one and two setups a little more inward, to give space to player 3 and 4 controls. I was more concerned with people crowding, and while I dont think there's anyway around it, would like to give the most space possible, while leaving the trackball room to operate.
Thanks for the reply.
