I found one! A friend asked me for a seperare Tate-Card to switch to when using his Tate-Display. Simply use the Arcade-Sytem instead of seperate Mame and FBA-Systems. Enter a game with Mame2003-core, activate rotation and save the system configuration file (not game or core override!). Done. The rotation setting will also apply to all FBA-games.

@langest said in Possible to rotate screen per rom file?:

Now I am only wondering, where should I put the rom specific file?

As the posts above said - and it's also mentioned in the Docs - , next to the ROM file.

@cybermrc you probably figured this out by now, but the cocktail switch only serves to flip player 2 upside-down. It won't induce the initial rotation.

I'm thinking about a cocktail table and was wondering if you ever figured it out?
