I've built one two player standup arcade machine already (dual trackball, dual 8-way rotary joysticks).
The last couple of years I've had this idea nagging at me to build a sit-down style cab for driving games and flight sim games. I like Afterburner (obviously) and G-LoC. And of course all the old driving games as well.
My wife gave me a Playseats leather seat and mounts for driving controls and pedals for Christmas last year. So I've slowly been collecting pieces. I now have a 22" widescreen LCD and a decent PC to drive everything. And I've got an old Microsoft Force Feedback II joystick.
So I'm planning to mount the steering wheel and pedals on the seat, and the joystick on the right side (as a sidestick) and a throttle quadrant on the left side. This will be used not only for MAME games, but for other PC-based games and sims as well.
But I'm tempted to go further and add a bit of motion to the whole thing. I'm doubtful that any version of MAME has support for this as the vast majority of games wouldn't benefit from it anyway. But for the PC-based games and sims, I think this might be cool.
I have built a couple of fixed base flight sims at work with real aerodynamic data and dynamics. So I understand how these work pretty well. I may go grab a copy of X-Plane at WalMart for $20 as the flight sim. I'm pretty sure I can extract the parameters necessary to feedback to a couple of servo motors.
So finally my question.....has anyone else done this, and if so, do you have recommendations on cheap motor hardware, etc?
