By the way, it doesn't require 4 inputs like people assume. The way it works is it uses 3 switches, and if NONE of the switches are on, then that is the 4th gear.

Ouch... MAME doesn't work that way, so you'll probably have to tinker with the source to get it to work, or hack on a fourth microswitch.

Sure it does. Think about it. If NO gear switch is pressed, then which gear would a game default to? Gear Zero? No such thing.

I haven't played a four-gear MAME game for a while, but I think they've been set to treat the gear buttons as press and release to change gears, just as Pole Position is modified to use two press and release buttons rather than the correct "button held for one gear, button off for another".

Yes, AFAIK.  The only game I can say 100% works like this is Night Driver.  So if no microswitch is activated the car will be stuck in whatever gear was last selected.  You could probably work something out using the NC contacts of the microswitches tho - if all NC signals are go then have that activate a 4th input.

I believe the Hard Drivin' shifter is very similar in looks to a Pole Position shifter, but 4-speed also.  I should be receiving one fairly soon for my Pole Pos. control panel, so I'll know for sure soon...

OK so i researched it a bit deeper. I'll try and do this next time rather than shoot my mouth off.  ;D

MAME tolerates keeping the gear button pressed. Now if I could find that damn shifter I could tell you if it's possible to add add a 4th switch to it!
