I have noticed that a handful of arcade ROMs will not launch successfully from the Attract-Mode menu, all of which are running under MAME 0.106. These include:
- Gauntlet (2 Players, rev 6)
- Teenage Mutant Ninja Turtles - Turtles in Time (2 Players ver UDA)
It's not clear whether the culprit is the same in each case, but they all behave pretty much the same way: basically, the screen goes black for a moment, suggesting the game is loading, then it immediately returns to the Attract-Mode menu.
Being a newbie, I'm not sure where to check for debugging info that might shed some light on the problem. Does anybody know what might be going on, and more generally, how can I see the error output for failed ROM loads?
