DaveMMR, that's why I made my panel a few more inches wide and deep for the purpose of playing GT & Bowling without breaking all my fingers.
My cabinet's a replica of Centipede so widening/deepening the CP can only be done by completely breaking the lines of the original (plus some reconstruction). Not worth it for me for GT.
To answer your question about mouse buttons, I am adding two to my CP cause I plan on using GameEX as my FE and I will be using the CAB as a jukebox and also to browse the internet from time to time. The buttons will be black and won't be too visible with the art I'm putting on my CP.
Right, but I still say they're more than expendable if you're using other FEs and don't use it as a web browser. And if you use an OptiPac (or reconfigure inputs via software/hardware/hacks), even if you do want/need mouse buttons, you can always use the main buttons for them. I only bring this up as a space-saver/button-reducing tactic.
Ka-razy Kenny, did you provide the Height/Width on the panel? I didn't catch it if you did. With encoder shift buttons (or moving them off the panel), you really only need a couple of start buttons and then get the spinner from GGG* with takes a whole lot less space. This way you'll have plenty of space to work the spinner. But the best way to test it is to make a mock-up on heavy cardboard, or even cheap wood (don't tell anyone, but I actually cut two "test" panels as I had extra wood that could very well be upgraded to final for testing purposes -- I called them dress rehearsals) and "feel it out".
*If you already bought a spinner, then forget that sentence.
