my preliminary control panel:
the two center sticks (p1, p2) are top fire for battlezone
the thumb buttons on p1, p2 are for neo geo
I may remove 2 buttons (leaving only 4) from the side sets of controls (p3, p4) if there are no 4 player 6 button games worth playing
the grey circles are spinners, ideally at least one push/pull spinner
the numbers on the joysticks indicate the number of ways they go (I may make changes to these like make the trigger sticks analog (ST Trilogy), or the p3, p4 sticks u360s, are there top fire u360s?)
no pinball buttons (clutter)
the white buttons are pause
the purple buttons to the upper right of the right spinner, and the upper left of the left spinner are stop/quit (and must both be depressed for them to do anything)
the other purple buttons are admin buttons (I will lessen the number of these as I learn more about how to navigate mame
I will use controller adapters for game controllers (nes, snes, genesis, saturn, etc... as I have plenty of (too many) controllers for different systems)
Ideally the trigger sticks are authentic tron sticks (with 2 topfire buttons for maximum compatibility), or at least tron handles on new shafts and mechanics
the trackball will be either a U-TRAK (lit) or a 4.5" atari one
the black buttons above the trackball are for mouse buttons, but if the situation arises, I want to be able to remap parts of the p1, and p2 control schemes to mirror these and to allow for leftys
I would also like all these things (minus spinners) to be lit by software controlled rgb leds so when certain controls are used for a certain game they are lit, and the other ones are dark.
that means the button colors here will not match the final design
edit: each button layouts' set of red buttons (not the 4-way) should be removed (old pic)
