Okay, we're building our first control panel at work (and the cabinet will follow). What we're after is a CP that's versatile, without being excessively huge, crowded, or expensive. Here's what we have (or have ordered) so far:
2 T-Stik Plusses. These will each have 6 buttons by them, and will be close enough to each other to work for Robotron, Black Widow, Crazy Climber, etc.
3-inch Trackball
Vortex Spinner
We also have some additional buttons for coin, player start, admin stuff, and to put near the trackball (a la mouse buttons). When we build the cabinet, we may put in a couple pedals, and use the spinner for driving games.
It seems like this should cover the majority of the games in MAME. Four-player is not a big thing for us - just single player and occasional two-player action.
What types of games will we miss with this setup? The things I can think of are:
Joystick + spinner (e.g., Tron, Mad Planets) since you can't hit the buttons at the same time. Trigger sticks seem really pricey, and even top-button sticks seem a little high. Anyplace I can get a good price on something like this, or is there some other solution I haven't thought of for these types of games?
Analog stick games. Are there any that can't be played pretty well with either a trackball or 8-way stick? I thought of using a PC analog stick (with trigger and thumb button) for the analog and trigger stick, but I tried moving the ship around in Mad Planets with the PC analog, and it felt pretty useless.
Gun games. Not really a big deal for us (and some of these work okay with a trackball).
Any other types of games I'm overlooking? I don't expect to cover every single game, but we'd like to make the CP as versatile as possible, without getting too pricey or crowded.
