borderless gaming actually upscales it very nicely - but unfortunately makes the trackball out of control. i'm guessing it has to do with the way they've implemented rawinput/trackball support. it doesn't seem to work quite like it should with a trackball. you slide your character over and they keep sliding until you 'center' it, which shouldn't be necessary, as the character should stop moving when you stop moving the trackball. same with the test menu.
Not perfect, but tried to pull a clear logo from the arcade flyer if anyone is needing one
Also threw together a bezel (7z file for original size). used borderless gaming to upscale to full resolution, then used reshade to make game 4:3 and add border. Looks good, but as I mentioned above, borderlessgaming makes the trackball go nuts.
