I had read about that fractional pixel online, and the bit does seen to exist in the vram (3 bits color, 3 bits intensity, one other bit). I don't think it ever got implemented all the way through. If it works as described, it should cause the right edges of polygons to appear with higher resolution than the left edges, particularly on black (blank) background. I've got an I, Robot in my living room and have looked for this visual difference and can not see it. Doodle City even provides the opportunity to move and rotate objects, so even with direct control of object and orientation I can't see it. Apparently there were other things that never got finished with the game too.

See my reply above... there is a 1/2 pixel being kept track of... looks like it indicates the pixel is "wide" and takes up at least half of the neighboring pixel to the right. This seems to delay the latching of the color to the monitor guns by a half pixel cycle. I agree that if it's there, its hard to see (I found some actual arcade footage online). I wonder if that's due to issues with the lower res monitors? Would be interesting to ground the 1/2 pixel signal pin and see if that has a noticeable effect on the screen visuals.
