It technically uses an optical encoder, but is limited in travel and reported to the PC as an analog controller no different than a pot.
The problem with the arcade games that used 360 degree wheels is that the wheels could spin endlessly and had no real center point.
The game only knows if the wheel is moving left or right and how fast. It doesn't know where center is or how far the wheel is turned.
If you crash in Pole Position, whatever position the wheel is in becomes the new center point.
So if you're playing on a G27 or any limited rotation wheel and had the wheel turned all the way left when you crash, the new center point is all the way left.
To keep the car going straight, you'll have to hold the wheel all the way to the left. It's then impossible to turn the car left because the wheel can't physically move any farther left. The original wheel spun endlessly, so it wasn't a concern.
Personally, a workaround for this is one HACK I would like to see in MAME.

I am aware of this problem. Did not know about the 270°-optical behaviour of the G27 (i prefer to use hacked analog pads).
I made some test in the past for RacerMAMe to face this but never ever ended with real solutions for this.
Anyone have tried to use joy2key to simulate a mouse movement with the pot and solve the problem before i start to made some (useless?) attempt with it?

Yes! Me! ;D
Joy2key can help to control optical games with a pot wheel (I have almost succesfully played championship sprint and pole position on my cab today) BUT it has a big disadvantage when used for such pourpouse: the emulated mouse speed is pre-defined by the user and is not variable with the pot position. Do you know if there's another (freeware) mouse emulator that can simulate a variable speed of the pointer?
