Thanks for your detailed answer.

It didn't work, maybe there is another way.

It didn't work with the bat files, but, I can create a shortcut for the bat file, and if I choose it in the dropdown, it works!

So thanks again, without your answer I wouldn't have figured it out.

Hello,

I launch a lot of games with different emulators using bat files.
Is it possible to make a list of this bat files grouping them as a system, and launch them using mgalaxy?

Thanks for your help
