Do you need any scavenged pole position parts? I think I have a few control panels and pedals left (I had like 6 sets but they have been really popular with people who have come by to buy other cabinets).
At this moment, I'm not too sure. Depending on what the software requirements turn out to be, it will dictate what the hardware requirements will be. When you say you have a populated Pole Position CP, what does that include? Steering wheel, buttons and shifter? Do you have the pedal as well? (If so, I would love to hear what price you'd be willing to part with them for. PM me, please.)
Cool! Have you decided on a development platform?
I haven't given it enough thought as yet. As I mentioned, I'm no programmer. I can do some basic work in Flash, in regards to making images and moving them, but as for having them react to inputs, this is something I don't have experience with. My Wife and I were talking last night, and I joked that if I really wanted to keep costs down, I could omit the internal hardware altogether... So, technically, all I'd need to do is build the shell, complete the artwork, install the steering, pedal and buttons, and slap one of these on the front:
Then, we just let it sit.
