Finally getting around to trying this out.
OK, I have 3 gamelists for MAME, and I am only considering MAME at the moment.
All games
Horizontal
Vertical
I can switch off the 'All games' List in the game lists tab - thats great.
My monitor rotates from its normal horizontal position 90 degress anti clockwise to give me my vertical display.
I have assigned a Panel button in 'controller/joystick/advanced/switch orientation' and 'flip orientation' so when I press this button the display rotates to the correct orientation. So it switches it - displays it upside down, then flips it - showing it the correct way.
Is this the best way to do this?
Also - I cant seem to get the correct gamelists to display for each orientation, it always seems to display both lists - how can I lock the horizontal list to horizontal screen, and vertical list to vertical screen?
Im not sure how controller/controller mapping works - can anyone help me out with this?
Thanks
