My Rail driver controller doesn’t seem to work with the class 142. No buttons work at all, can’t even sound the horn. I have calibrated my rail driver. Any help would be much appreciated
Standard AP disclaimer it doesn't mean you can't use them if you have the right software, (Linked above).
This software doesn't alter anything within the sim it's its own independent software that interacts with the raildriver.dll so I find it very hard to believe that the software "messed up your Sim".
I am in the process of building another version of the rail driver, the first one became over complicated, but I did find that to use AP products, I had to map the joystick (potentiometer) output to key presses for it to work. So yes it can be used with joysticks, you just need to use an interface . I did use CobraOne's raildriver code to connect to the TSC game engine and an arduino connected to the joystick.
Well I can assure you it did as it messed my keybinds up even after I removed the file you copy over. Believe what you want I know what happened in my sim
