EDIT: Still, how did they add the ball behind the rings counter? If it was added by the ad people?
The ad people could have added a second rings counter, on top of the ball and existing rings counter.
We do need a higher quality video, if we want to be sure whether or not it's real.
Remember that this is a PAL capture from Sonic 1. Making pixel masks is almost impossible. Try doing it in Photoshop, and you have to make alpha masks, and still it will look wrong.
Time to do the Sonic math to see if this is possible. Imagine the diamond is always 16x16 pixels big, even when rotated. That means 4 cells per frame. 16 frames per rotation. 64 rotation states (90 degrees).
4 * 16 * 64 = 4096. That's 150% of VRAM. Remember that the level art takes 46.8% of VRAM, and SAT, HSCROLL, and SCROLL A/B must fit VRAM too.
Or let say this is animated pattern just like the big ring. Uncompressed pattern takes 32 bytes per cell. 32 * 4 * 16 * 64 = 131072 bytes or 131 kb. That's 26% of Sonic 1's ROM size.
You are welcome to correct my math if needed.
Here is a picture simulating all rotation states. Remember that it only shows 8 of 64 rotation states. Good luck adding that in your hack!
