Okay that makes more sense now, so yeah I may as well remove that "Rotate For Vertical" option.
The "Include Vertical Bezel" option is for horizontal users that want to have a "Mame" logo down the sides for vertical games. It's just so there are no black strips, but the Mame logo instead (have a look at the attached image, it shows what image is included with that option).
Okay I'm going to have to recode some of this.
So far you've given me the values for a 1280x1024 vertical display, So now I need to know the values for the rest of the resolutons. I really need to support them all to implement this correctly, any ideas or is there an obvious pattern I'm missing here?
Horizontal Monitor Orientation
320x240: Horizontal Game: L=0, R=320, T=0, B=240, Vertical Game: L=?, R=?, T=0, B=240
640x480: Horizontal Game: L=0, R=640, T=0, B=480, Vertica Gamel: L=140, R=500, T=0, B=480
1024x768: Horizontal Game: L=0, R=1024, T=0, B=768, Vertical Game: L=?, R=?, T=0, B=768
1024x960: Horizontal Game: L=0, R=1024, T=0, B=960, Vertical Game: L=?, R=?, T=0, B=960
1280x1024: Horizontal Game: L=0, R=1280, T=0, B=1024, Vertical Game: L=?, R=?, T=0, B=1024
Vertical Monitor Orientation
240x320: Vertical Game: L=0, R=240, T=0, B=320, Horizontal Game: L=0, R=240, T=?, B=?
480x640: Vertical Game: L=0, R=480, T=0, B=640, Horizontal Game: L=0, R=480, T=?, B=?
768x1024: Vertical Game: L=0, R=768, T=0, B=1024, Horizontal Game: L=0, R=768, T=?, B=?
960x1024: Vertical Game: L=0, R=960, T=0, B=1024, Horizontal Game: L=0, R=960, T=?, B=?
1024x1280: Vertical Game: L=0, R=1024, T=0, B=1280, Horizontal Game: L=0, R=1024, T=256, B=1024
EDIT: I've put all the code in place to do this, now I just need to put in the values.
