One more bit of information - on my Power Mac G5 1.8GHz (single), with no MAME OS X folder in Application Support to begin with, it takes MAME OS X thirty seconds or more for each game to determine that the game is not there at all.
And while it's checking each and every game, I have the spinning beach ball and MAME OS X is completely unresponsive. I had to force-quit it.
Edit: I put my 394 romsets into the right folder and ran MAME OS X... and then I decided to kill it five hours later 'cos it had only gotten up to the Cs. There's definitely something wrong with auditing. If I can get a chance soon, I'll have a look at the code.
