Thanks GEEKiDoS

Usage:

• Copy MU3Input.dll into game folder
• Open segatools.ini and add following lines:

[mu3io]
path=MU3Input.dll

[aimeio]
path=MU3Input.dll

You can use Jetbrains Rider or Visual Studio to compile.

I Move the project to Arduino so you can use Arduino upload it not the Visual Studio.
