Ok. Now we're sure we're talking about the same thing. But it isn't that simple. The c2p I have cuts the work in two halves : high 4 bits and low 4 bits. I can't do the exact same thing in the reverse order, else half of the data would have been missing, and writing 4 bits would be slower than writing a full byte.
I dunno if this is clear, at least I understand myself

Ahem... it looks like if I don't have enough registers to keep the 24 plane data at once...

They don't produce mess by pure laziness. The machine's architecture has its part.

Hopefully you're still here. Else I would have felt soooooo alone.
