I'll let everyone in on a little secret...
The USB Gravis GamePad Pro controller (charcoal grey in color) is a PERFECT controller to hack.
Why?
- $14.99 normal price at BestBuy (occassionally on sale for $9.99 !!!!)
- 14 DISCRETE Digital Inputs (4 Direction, 4 primary button, 4 shoulder buttons, 2 "start/select" buttons)
- Long Cable
- USB, not old gameport (allows up to FOUR pads connected to most motherboards that have 4 ports, without need to cascade and the problems that ads)
- NO special software if you use Windows (no sidewinder calibrating/drivers)
Disadvantages:
- NO Pure DOS USB support.
For your project, I'd just go with something like this.
If you make removable control panels, on sale at $10 each, it's CHEAPER to buy 1 pad per panel, and then just disconnect the USB rather than buying molex connectors to disconnect the panel from it's mate like others do when they hack into say the $45 IPAC's.
