I don't know if it has been fixed since, but at some point, there have been a bug in MAME (if i remember well, it was something like the syscard was loaded after the CD, or something like that) having exactly the same behaviour as yours, and the only way to get around it was to press F3 (reset) once you are on the black screen (because now the syscard is correctly inserted and it will work on next launch).
