Well, you need to look at what the control requirements are of the games. I picked up a gutted Pole Position cab with no monitor, but with the steering, shifter and gas pedal intact. I put a simple PII 233 PC running dos in it, hacked a mouse and put a 20" PC monitor in it. I also put a switch under the pedal (really only give gas either full on or off anyway). Running DOS and an older version of MAME, recompiled with a change to the PolePosition driver so that the Shifter works(instead of 2 switches, hi and low, it reads one switch...open,hi...closed, low). This works great and I can also run the other "dial" control games like Super Sprint. My idea (and the reason I started the thread) is that for newer games(like Chase H.Q.), these games don't look for dial input, but rather 8way joystick input, which you can emulate with a USB PSX steering wheel. I'd like to get another stand up driving game, like OutRun, and get the newer games running in this cab. I figure it would be better to use a cab built with a steering wheel instead of attaching an "home use" PC steering wheel. Haven't had too much response, so I guess no one has done this yet...
Hopefully someone has and can share their thoughts....
