I got you project almost working on Windows 10. It loads, all Libs are found but then:

Workaround:

    for i in range(0, npixels):
        try:
            (pixel,) = struct.unpack('<b', bm[pixel_index:pixel_index+1])            
        except Exception:
             pass   
        rgba = palette[pixel] | -16777216    # set alpha to fully opaque
        img += struct.pack('<i', rgba)
        pixel_index += 1

It only happens with "HD" Textures from P99, no errors with original rof2.
