In that particular game, hit the tab button, go to video options, and then select "rotate view" until the display is correct. These settings should get written to the game's .ini file, and next time you launch it, it should come up oriented properly. This is a MAME thing, not a mala issue.
I'm surprised you've only got 1 that comes up wrong! I just re-configured my cocktail machine, and I've got 325 roms on it, and I swear I had to rotate 320 of them!
edit: I should point out that this is using a newer version of the command line MAME. Not sure when they added the video options, but it's at least from 0.111 onward.
