Let me pose this question: Isn't a 360 wheel essentially a spinner with a steering wheel attached to it, or is there some vital part/assembly I'm not understading? I'd like to use an actual steering wheel, but I may just be a victim of overamitious brain activity on this.
Not positive where you're going with this, but . . .
Yes basically, a 360 wheel is essentially a spinner with a steering wheel attached. They won't work well for 270 games and a 270 wheel won't work at all (generally) for 360 games.
Keep in mind that the shaft on a 360 wheel is usually thicker than a spinner would require to account for the added weight of a wheel as opposed to a knob.
I'm still considering picking up a few of these (the guy's willing to drop the price to $18/wheel). I think with a multi-monitor videocard (Matrox Parhelia?) I could send the game info out to multiple TV's, or at the very worst, I'd have a bunch of extras to scavenge parts from!
You could, but I'm not sure that gets you anywhere . . .
For console emulation, or for multi-player 270 games (if there are any), the game is set up to show both cars on the same screen (or MAME would modify it to), so all you are doing is having the freedom to physically separate the two wheels.
For single 270 games (OutRun), there's only one car, so you just end up with the guy on the left being able to fight with the guy on the right about which fork in the road the car will take.
