Event: Chaos Communication Congress 28th (28C3) 2011
Abstract: C64 "demos" were the root of the whole demo-scene-thing and they are still the main force keeping the C64 alive today. Audiovisual pleasure, still pushing hardware limits, still exploring different ways of expression. But what is typically happening inside the machine when you watch a demo? What effort is needed to entertain the audience? This talk will give you an inside look at the steps taken for the award winning demo "Error 23" given first hand by one of its main programmers. This talk extends previous talks and documentation about the Commodore 64 and its demo effects by adding real-life challenges and experiences to it. What were the basic ideas? What obstacles were on the way? How did they get solved? 6502 assembly knowledge is really not required, some general understanding about assembly and low-level computing will be useful, though (think of stack, timer, cycles...). This isn't about theory, this is for real ;)
