Cannot force res Star Wars Bounty Hunter [GC]

[mblotter]

I'm having a difficult time forcing resolution for Bounty Hunter. It's an NTSC ROM. Other titles, such as Pikmin and Super Mario Sunshine, work perfectly fine. Alas, this title does not. Instead, and I can provide screenshots if absolutely necessary, it seems as though the basic resolution will be rendered and scaled. I've tried on D3D9/11, OpenGL, nothing seems to work. Fullscreen resolution is set to my display's native, 1920x1200, with both auto aspect and force 4:3. Internal resolution is...well, I've tried all of them, and on all backends, with no change. Am I just screwed, or is there possibly a setting I'm overlooking? technical info is as follows
