For what it's worth, the interleaved modes on atari works like this: The bitplanes are interleaved on 16 bit big-endian word basis so if you have two bitplanes, bit 0 of the first 16 pixels would be in the first 16 bit word in the display memory, bit 1 of the first 16 pixels would be in the second word. With bit 0 I mean as masked out by & 0x0001 in C, and bit 1 as masked out by 0x0002. The Atari ST line support three resolutions by default: 320x200 4 bit planes 640x200 2 bit planes 640x400 1 bit plane
Okay I have been think about the other modes and can't figure out how they would work. Could you do a run down to get my hamster running? ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
