Good question!dma wrote: How could this work with sprites? Would those also be two-images-flickering based or not?
I tried some full experiments (on the other thread) with scrolling game background demos from Arcade boxes and had started on sprites after that, but didn't complete the work on sprites (distractions!). I worked out some patterns and preshift rules and a mocked-up test - but that's about as far as it got.
Anima has been looking into this also - managing flicker while things scroll/move - so there could be some additional ideas/conclusions appearing here soon.
BTW if the connection hasn't been made already, this project has also been using the technique since quite an early stage in its development - so we know it works on 3D stuff too.

Sprites have special issues since they will be moving at 25 or 50hz and potentially in the opposite direction to the scrolling, unlike 3D graphics like this which take a few frames to compose an image, and the interlace is highly decoupled - not so fussy. Although converting the textures was painful.
