It doesn't add up. Changing numdw must make a visible difference, it determines how many pixels are cleared (multiplied by something).

I don't think 0 is even allowed. Try 1 and see how large part of the screen is rendered correctly. It should be 64x64 or something like that, I don't know for sure. Knowing that size would come in handy. The rest of the screen should be corrupted.

With 1 the whole screen is corrupt and mostly black - but you can still see part of the gears flickering though it's hard to catch in a screenshot.
