Hi Calamity,
Yes, I am also getting a black screen.
This time I tried to add -resolution 2560x0 in the command line to run the game, and also tried the same adding the "resolution 2560x0" in mame.ini, but had the same result.
When this happens, I can hear the standard Windows 7 sound as if a USB unit was unplugged. I just added a new log and my mame.ini zipped file. Maybe this will help.
I didnt realize about this until by curiosity I read this post and decided to try.
Anyway, the workaround is easy, just press the start button and play the game
Thanks a lot for your time and efforts!!!
