There is also something i dont quite understand.
From what i know the most efficient usage of blitter requies triple buffering.

Does it mean if we have for example 320x356 frame buffer in 4 bitplanes we need 3x40kB=120kB of chip Ram??
Yes, but you need more than 320x256 because you need extra ram for scrolling.

Don’t forget you also need ram for the sprite masks.
