 "And now for my next number I'd like to return to the classics"
 This is indeed a classic, released by SCA in April 1987.
 This patch was requested yesterday by Retroplay on EAB and rightly
 so because this demo has a very small yet very annoying problem.
 See below.

 I'm quite surprised how clean the code actually is, especially considered
 the release date and that SCA originally was a C64 group. Most C64
 coders that changed to Amiga used all sorts of tricks such as
 self-modifying code, direct ROM jumps etc. that were useful and perfectly
 fine on 6502/10 CPU's on the Amiga too. You know, old habits rarely change.
 Only problem: on Amiga these tricks were mostly causing more harm than
 good and most of the time they were completely unnecessary anyway.

 SCA did quite a good job here, very clean code that had only one major
 flaw: the LED was toggled constantly, no problem on old A1000's that
 don't have a lowpass filter, on all other machines it completely spoils
 the demo. I have of course fixed this so you can now enjoy the sound
 the way it was meant to be enjoyed.

 I also think that the 4th disk is broken, the file is too short!
 Each big data file contains the mumber of chunks in the first word,
 for part1 this value is 24 which means the file size is 24*32768+2
 bytes. If you check the sound1 file in the data directory you'll see
 that it has exactly that size: 786434 bytes.
 For disk 4 this value is 19 so the sound4 file should be 622594
 bytes long, however it only has a size of 504104 bytes which makes
 me believe that the file is incomplete.

 Originally, the demo would load 2 bytes from each data file to get
 the number of chunks and then it would stream the data. I have
 changed that, in this patch the demo reads these values from an
 internal table which results in less OS swaps.

 I also added an option to loop the demo, use Custom1=1 to enable it.
 If you don't enable the loop feature the demo will simply quit at
 the end (the original code would simply reset the Amiga).


 Enjoy this classic from HD now. More patches for real classic
 demos will follow soon!
