- Aminet game/demo/GloomC2P10.lha has source code for fast, CPU-only,
- 1x1 and 2x1, 6-plane and 8-plane C2P, optimised for 020s, 040s and
- Akiko. These routines use a "scrambled" chunky buffer.
-
- Aminet gfx/show/flick-1.5.lha has source code for fast, CPU-only, 1x1,
- 4-plane, 6-plane and 8-plane, linear C2P, with "dirty" list (array of
- flags indicating which parts of display to convert) optimised for 020s
- and 040s.
-
- If you want a direct replacement for WritePixelArray8(), try:
- ftp.funet.fi /pub/archive/comp.sources.amiga/volume94/graphics/c2p-1.1
- This is slower than the above routines, but much more general.
