I searched and couldn't find an answer to this.
Is there a way to have my layout set up so that on the list of games I can run regular mame roms but also mix in there some executables? I have some autoit exe files that perform some actions on my arcade cabinet that I would like to be able to launch from within AM. If not possible then at least I believe I can create a separate layout that hosts the scripts and launch from that screen instead.
Edit:
The homepage info states the following which I think is what I'm after:
Supports per-game customization of the game launch commandline (executable and parameters).
How is this implemented?
