Did you try it with QPC2v2 or just with v1? v2 should be able to
handle it.

This is correct. QPC does have two modes for the 512x256 emulation:
640x480 and 1024x768. The first one looks awkward and the latter one
perfect. If the graphics driver reports that it can handle 1024x768
(which many Laptops do although their screen is too small) QPC prefers
this mode.

If the graphics chip is capable of scaling you can open QPC in
512x256 windowed mode and manually maximize the window.
