Initially I had my screen and Windows desktop set to portrait mode and, while AttractMode works fine in that arrangement, I am finding several of the game I am trying to run in MAME have issues in that mode. As a compromise, I've found that if the desktop is in landscape mode and I then run MAME rotated, all games work as expected. I am planning on mounting my monitor vertically in my MAME cab.
The problem with this is that AttractMode appears in landscape mode when started and would obviously look wrong when the monitor is eventually mounted. So my question is this: Is it possible to start AttractMode in a rotated mode upon launch? If so, how do I go about doing so?
Thanks!
