ArcadeOS + ArcadeVGA and Horiz. Monitor Prob.

[dax]

I'm having a problem.  I am running ArcadeOS with ArcadeVGA with a horizontal arcade monitor.  I cannot figure how to flip the game 90 degrees to play vertical-monitor games on my horizontal arcade monitor.  Does this have something to do with the default VESA mode setting?  I can change the resolution in ArcadeOS's configuration by default and for each game individually, but I can't seem to find a setting that flips the game if it is a traditional vertical-monitor-oriented game.

I'm running .36 version of MAME with the latest ArcadeOS.  Any help would be appreciated.  I'm not sure if this is a MAME issue or a .CFG issue or something within ArcadeOS.  Any help would be appreciated.

So the games are playing vertical already, and you want them in a horizontal state, did I read correctly?

In the menu, unless you've already locked it, you should be able to hit (I think) button 2 to change the orientation of the game.

Unless you have 'autorol/autoror' in your mame.cfg.

Games that are vertical are sideways on my horizontal arcade monitor.

In one I changed the resolution and it was fixed.  In others no resolution makes a difference.  One game I was playing (tetris set 1) was perfect horizontally, and then the next time I exited and returned it was vertical (rotated 90 degrees and now sideways on the monitor) and I wasn't able to fix it. 

I think this is a sign that I should just dump AOS and try something different.
