How to run a script whenever switching platform?

[MowTin]

I'm hoping there is some hook where I can add a script that runs whenever a user chooses a platform. 

I have MAME and Windows games. My windows games are imported from Steam and Microsoft Store. 

I have an Ultimarc ultimate io encoder. It load a different config through a command line parameter. I have on config for keyboard and another for xbox gamepad. 

From the posts I researched, I could replace my MAM emulator exe with an ahk script and for each windows game wrap the exe in a script. I'm hoping there is a better solution.
