   What a cool talk!

   Will you be doing a part 2 next year?

   It would be very cool if you could cover how some demos used the CPU in the 1541-II to do the demo effects on the screen. To my knowledge the CPU in the 1541-II was a lot faster than the 6502.

   Also how was some demos able to get text scrollers in the borders? Some even had vertical scrollers.

   Some games (Chessmater 2100) had no files even though it was a 2 side disk game. How did they do that?

   Or just how could crackers (Ikrai) take Last Ninja 2, whcih was a tape game, and port it to disk, without the source code?

   Or if you could perhaps show have Final Chartridge or Action Replay was used to make a trailer?

   @Louise:

   * Although the talk was quite popular, I very much doubt it that the Chaos Communication Conference will give me another slot for basically the same topic this year.
   * I know that some demos used the 1541 CPU for helping with floating point calculations to calculate fractals. The CPU in the 1541 was only clocked at 1 MHz, but it for certain workloads, it could help double the performance of the whole system.
   * Text scrollers in the borders used sprites.
   * Vertical scrollers… maybe sprites, maybe some other creative combination of tricks…
   * No files on disk: Since could upload code to the 1541, you could have it manage a custom filesystem that presented itself as “empty” to the normal OS. Or you could just do block-reads (”B-R”) without even uploading code.
   * Porting games from tape to disk: Reverse engineering is not all that hard if all code and data must fit in 65536 bytes.
   * Trailer??

   Can you please up a non-mac format of the presentation for the rest of us?

   Yes.
   My version of Keynote is too old to open the presentation.
