Am I missing anything or is it not possible at all to have a custom INI per arcade system or arcade can't be subdivided into systems?
I mean, for instance segas24.ini (Sega System 24) is not recognized by Mame, whereas crkdown.ini (Crack Down) is.
I've seen in the Mame docs that you can have neogeo.ini for instance, and it actually works. But I can't make it work with other systems (cps1, segas16, segas24, etc).
If not, it would be nice to be able to configure separately old systems from newer systems using totally different screens and resolutions.
