How did you figure this out?  I noticed while poking around in the MAME source that the analog pedal code is based on a dual axis system...but knowing MAME it isn't usually very accurate on inputs.  Just wondered if the original was actually dual axis (I should look at a wiring diagram I guess...)

That was about Out Run and you can see it in the ownersmanual on KLOV (in the disassembly of the brake/accelerator unit page).

This is about OutRun, actually, I misspoke, but you can tell from the way MAME is set-up that it it dual axis.

I based my statement on the KLOV write-up that shows separated pots for the brake and gas, but these COULD be wired in a single axis config.  My current racing pedals are set up this way - two pots, but single axis.

However, in MAME, (I think the Brakes are P1B2), if I map P1B2 to L Alt, I get brake lights (on the screen).  If I map P2B2 to J1 X-Axis -, my brake pedal works, but no brake lights.  This tells me the actual game is looking for an input from the brake pedal, either a switch/button or a separate pot, and since the assembly breakdown shows two pots in the pedal assembly . . .

Cool, I just wondered if you'd assumed 2 pots or MAME's input method was arcade acurate...your last description is very helpful tho, I hadn't thought of the brake light & separate switch/pot before, thanks :)

I just posted in the software thread that R37B16 was the last working System 16 build, FWIW!
