So I'm trying to get some driving games to work (Pole Position, Outrun etc..) and I want to use a single switch, or use the Normally Open/Normally Closed functionality to trigger the shifter, the issue is most emulators do this with a toggle, which is less than optimal when you have labels on the cab with H-L or some other designation, as it is easy to swap them, during boot etc...

So in Pole Position there's a driver polepos.c where you can comment out the toggle, and get it to work as originally intended, where when the switch is depressed it's in H or L, and if it's not it's in the other gear, so no confusion.

The issue is because I have to alter the driver file, I have to re-compile advance-mame from source, I tried installing the source code build for emulationstation, from retopie-setup, and that worked, but I don't know if that script deleted the source files once done, but I can't find the driver .c files.

So my question is, how do I add the "from source build" advance-mame, in my ~/advancemame folder, to be selectable during launch, where you can assign a mame engine, or is that even possible, am I barking up the wrong tree?

I was thinking of adding some symlinks into the ~/.advance folder, or copying it over wholesale, but I figured I'd ask here, because most posts are about rom configurations, and multiple rom folders, which is not what I want, I'm fine with 1 rom folder, and 1 configuration, but to run the source built advance-mame instead of the one provided by Retropie-setup.

Just compile it (and optionally install it) separately, then modify your arcade (or mame-advance , whatever ROM folder you use) launch configuration in /opt/retropie/configs/arcade/emulators.cfg and add an entry for your own modified advmame under a different name and with the correct path.
When launching an arcade ROM, use the Runcommand launch menu to choose your own advmame version by default and that's it.
