Maybe I'm wrong.
I noticed in some points of the Colecovision demo video that the character sprite moves behind objects and the TMS9918 does not allow to place a sprite behind the charset as it happens on the c64 instead.
I saw that they are not even sprites put at higher priorities.

How was it possible?

I suppose they just modify the sprite on the fly...

Too many cicles for CPU!

They clip the sprites on fly.
The whole game is designed around this feature

I suppose it’s costly, but if the game’s frame budget is accounting for it it can fit I reckon. In the end applying a mask to the sprite patterns is 32 VDP writes per pattern (with an AND applied to each write), if there’s only 4 or so patterns where this is applied then it’s not free (let’s say 10% of frame budget), but not impractically costly either.

Like in demo world, mixed hard/soft approach gives the most amazing result.
i have been surprised such technic has not been already made on colecovision (not sure for MSX 1 as it already had technicaly Amazing games).
To be honnest it's costly, i think rr uses CPU at 80%.(for ntsc, a bit less for pal)
