I have an internal version that has preliminar support, but combining sprite rotation with raster effects and keep good performance is not trivial...
Heh that's why SNES had dedicated hardware for that, and even then, it only worked as a raster effect on backgrounds! That's why the entire background is black in the first boss battle in Super Mario World - the rotating dinosaur boss, as tiny as he is, is actually a "background" in the system! (megamarc probably already knows this but I like talking about it)
Also if you did implement it, I would expect it to not have any anti-aliasing and be all pixelated and "twinkly" as it rotates around, the same way it looked back then
Back when I first played it as a teenager, when my best friend and I first saw that effect (on that boss actually, when the SNES came out), we decided to call it "pixel movement" because it appeared to be moving each individual pixel. We wanted to name it because we hadn't seen it before and it was something only the SNES could do.
