Short: Ultimate c2p/copperscreen replacement! Author: fischerj@informatik.tu-muenchen.de (Juergen "Rally" Fischer) Uploader: g sanderson ais gu edu au Type: dev/src Architecture: m68k-amigaos BLITTERSCREEN: The copperscreen replacement, aka ultra-fast c2p, without copperscreen limitations I took this from http://www.informatik.tu-muenchen.de/~fischerj/ It still has a few problems on high end machines (A4000) and is not very OS friendly, but it WORKS!!! Contains sources, examples and a demo! what is it ? Blitterscreens provide a CHUNKY 256-color 2x2 or even 2x1 screen, and all fullscreen! (AGA only, ECS could do byte-chunky 16colors, not supported yet). cpu overhead very small, cpu free for rendering, this method is even useful for 030! is it really like having chunky mode ? The cpu can copy to chunky buffer in longwords to chipmem, each byte beeing extended to a 2x2 pixel block by custom hardware. Imagine your A1200 was connected to a localbus-VGA. Copying to vram then would be slower (!) as you got to copy 4 bytes to get a 2x2 pixel block (VGA beeing fastmem changes nothing). So stop whining about not having a chunky screen, there is one! :) I admit it might be not ideal for a 040, but the 040 can do realtime-1x1-c2p while copying to chipmembuffer anyway. A 030-50 also might render faster than blitterscreen convertion.
