Dgame,
I already tried using this tool but it won't run on my arcade system, I just get an error saying I'm missing a file (Windows 7). So I ran it on another computer (Vista) and it seemed to work fine but I couldn't get it to to write a proper ini file that I could use.
Is it true that you can just copy your mame.ini file, rename it to the game you want to modify (umk3.ini) and then adjust the settings? Where would I put this new ini file? There was no ini directory for mame command line (I think version .135).
Thanks for your help
