Do you know how MAME address's multiple monitors? Is it like NVIDIA surround vision, or ATI's Eyefinity? (where its just one really wide screen presented to the application layer)
Or is it three separate screens, each with individual resolutions?
Stuff like this makes me want to chop the 'head' off the driving cabinet and make a triple screen sim pit.
Don't know about running different resolutions on each screen, but MAME has options for both 3 individual screens or to display all 3 virtual screens on one screen.
The former would work without the eyfinity stuff. If all your screens show as one wide resolution on the desktop though, you might need the latter option.
Either way, MAME has it covered.
On my widescreen standup cab, the multiple screen games display both screens on one widescreen monitor.
The cool part is that HLSL CRT effects are applied to each virtual screen separately so it looks more like two bulbous CRTs behind the tinted plexi.
My favorite is Punch Out with the widescreen rotated vertically and displaying 2 stacked horizontal monitors.
