I have had the occasional return from game where Mala exits to the right layout per the game that was just played, ie. horizontal game exits to a horizontal mala layout for about 1/2 second, then it flips to the vertical layout. It makes the same sound it makes by default when joystick is pressed in Mala. I either have to navigate to another game and play it to switch back or right click and use "switch orientation". That was fairly rare and was manageable.
Now, about one out of 10 times on game exit. the layout comes back both switched and flipped upside down. so, to see it properly, right click, switch orientation then right click, flip orientation to get it back. Its a showstopper for anyone using the games but me.
One change I made along the way was that when first playing with rotation I was rotating clockwise horizontal to vertical, and am now doing the opposite.
My settings are:
Mala 1.7.4.0 (I know, need to check out 1745 beta, no issues of this type noted on the release notes.)
Monitor physically rotates anticlockwise from horizontal to vertical
Mame config: auto rotate right is selected
Startcom plugin V 5.3.2: horizontal to vertical is set to rotate anticlockwise
Startcom rotation is by a simple batch file that runs command line commands for the motor control board.
In video options on games tab menu: horizontal layouts have no rotation, vertical games are CW 90.
I have played with these settings extensively and these are the only ones that work right to display the games correctly. anybody who has any ideas on this let me know - thanks.
