Okay.

Ah, okay. And those machine's gfx hardware would be designed to read
and write whole bytes?

Rather than getting a byte value, in planar you have to get 8
individual bits, and put them together? That what you mean?

Ah. XTreme racing kept wittering on about c2p routines...
Must have been, they used chunky to rotate textures quickly, then the
clever bit was quickly changing to planar...
Nice!

Yeah, cheers!
