Amiga Hardware Programming 12 - Bitplane manipulation, program structure, and the stack
We make our demo a bit more system friendly using SECTIONs and stack to preserve registers and give our a code better structure. Also explains a little bit more about how things are stored in memory and especially bitmap data. And our happy sprite is back! :) Errata: $dff007 is the low byte of VHPOSR, not "the clock register".
