That's funny, I think I'm trying to do the same thing...
Here's what I know. When you change settings for an individual game, it's stored in the INI file for that game in the INI directory.
How to get that file to load with the game... That's the trick.
Does anyone know?
I tried a bunch of command line options on version .70 of mame32.exe an very few work at all. I'm using XP, if it matters.
Can anyone help?
Thanks.
