How much would it cost to build a MAME cockpit?

[InsaneDavid]

InsaneDavid, what games did you put on your MAME driving cab?

I have some video of it here shortly after I got it up and running (it's still outside at the time). I'm running DOS MAME v0.56 since the computer is a Pentium II 350Mhz at 128MB RAM. That and I also wanted to be able to kill the power at any time without issue. The current setup, and the one I'll probably leave it at unless I replace the PC inside, is...

Badlands
Championship Sprint (Revision 3)
Danny Sullivan's Indy Heat
Fire Truck
Konami GT

I bought my cabinet as a Pole Position so it has all the builds of both Pole Position games, that's also what I mostly play on it. The two paddle games I have on there as an occasional diversion. They work well enough using the wheel as a giant spinner, which it is anyway. Everything is run through a PS/2 mouse PCB. The steering wheel is basically the horizontal axis of the mouse with the shifter (PP's are single button, HIGH, shifters) to one mouse button and the pedal (converted to digital input) to the other. The coin mechs are wired to a single button keyboard hack and the keyboard itself is accessible through the lower coin door. The cabinet boots into DOS and a game selection menu, type in the selection you want on the ten key pad and away you go. It's like virtual board swapping through the coin door. I tried some FE's but they all caused the games to choke for one reason or another. Besides, it's not supposed to be a MAME cabinet really, just a Pole Position that can run other games. I also tried having it load Pole Position automatically via batch files but the game would choke. The system likes to idle at DOS for a moment before loading a game it seems, no big deal. Also my game list is due to the specifics of the system, the limited control surfaces, and the build of MAME.

I chose games that would work with a single pedal, single gear (as in only needing a button held down to upshift, default in low gear) and wheel. I've made no modifications to the control panel or cabinet. Games like Super Sprint have the Start button set to the pedal in addition to acceleration. I'm using a recompile of DMAME v0.56 that supports proper shift setup, as in the car always being in low gear unless the shift button is held. Been playing it for about two months without a single problem.
