I don’t know how your led part of your controller works but my controller use a program called comopen,which run before the game start.At same time I also add led part into segatools like this:
[led]
Port=4
rate=1000000
I am not sure it’s usable for your device.
make sure your device com port same in segatools.ini, device manager and start.bat, and be different from aime com port if you use external card reader
