This is probably a really stupid and simple problem, but I can't find any documentation on it. I use no frontends, no mame32, I just like to use standard, normal MAME that opens up in a full-screen, DOS-like UI, and I need to have it display only working games (I like to navigate and load random games via controller during gameplay). Is there any text I need to add to the ini file that would make it work the way I want it to? And also, is there a program out there that will delete all non-working ROMs from my directories? Thanks!
