Yes, it’s the normal ET4000 driver binary from Idek, but attacked and patched at runtime as it starts up.
Pretty much any VGA card will work in standard VGA modes (320x200x8bpp, 640x480x4bpp)
Some cards have SVGA support.
And only a few with hw accelerated VDI;
Cirrus GD5426,5428,5429,5434
Western digital WD90C31
Here be dragons;
