Sorry, I thought it was in there. I guess it used to be a test driver prior to the gamelist overhaul.
You see now we don't have testdrivers, we have all games added in the normal gamelist. And some with "not working" flags.
Why is this an issue? Because the only, and I mean the only way you can get a list of non-working games is to use mame's -gamelist command, which is very obscure and not used by any front ends or developers. So when a non-workign game is upgraded to working status it can often get overlooked and not added to the what's new text.
I understand why the mame developers made this drastic change, but it's quite annoying for all parties involved, including the developers themselves. I had to re-write parts of the fe because of it.
Ok I'm done.
