Vertical screen flip

[ratsflif]

Hey,

Just installed groovymame and the ati drivers on my vert vga cab, wow it looks amazing.  The only problem im having is with the vertical option in the ini, it rotates the screen counter clockwise 90 degrees, is there a way to make it rotate clockwise 90 degrees?  My monitor is rotated ccw, as all the boards i have play in that orientation, I have tried messing with the mame ror with it set it to horizontal but then the game doesnt display correctly.

Thanks

Nvm, After messing with it some more, flip x/y works in the mame options, i thought i had tired it before but it works great now.
