 This install applies to "Megademo"  1991 Zeus.

 Requirements:
 -------------
 This install requires WHDLoad and RawDIC to be in the path.
 These programs can be found in the WHDLoad package.
 To install from a different drive than DF0: select installation mode Expert.

 The installed demo requires 0.5 MB ChipMem (+0.8 MB for preload).
 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD (real files!)
 - Decrunchers (PowerPacker) relocated to fast memory
 - DMA wait in replayer fixed (x9)
 - Byte write to volume register in replayer fixed (x6)
 - Self-modifying code fixed
 - ButtonWait support for loader picture
 - Intro can be skipped with CUSTOM1
 - Random generators recoded
 - Bplcon0 color bit fixes (x22)
 - Blitter waits added (x4)
 - DMA settings fixed
 - Interrupts fixed
 - NewIcon (created by me)
 - Source code included as usual
 - Quit option that works on 68000 machines (default key is 'F10')

 Guess what I did when I arrived (very early as usual) at work today. :)
 Always nice to start the day with some fun coding so I just patched
 this demo which was released at the Maximum Pleasure party in 1991.
 Code is very clean, only some minor things had to be fixed such as
 the usual replayer bugs and stuff like that, some blitter waits had
 to be added too in the init parts. The random generators relied on
 the raster beam position so they produced not too good results on
 fast machines and had to be recoded too.
 The Bplcon0 color bit was never set, this had to be fixed too of course
 but other than that this was quite an easy patch to do.
 Most of the files were crunched with PowerPacker, I have relocated
 the decrunchers to fast memory for better speed. 

 The demo is short (just 4 parts plus intro) but nice, the loader part
 is quite nice as well. It features progress bars for loading/decrunching,
 I have disabled the progress bar for loading for obvious reasons.
 ButtonWait is supported for the loader picture, if enabled the demo
 will not be started until either mouse button has been pressed.
 Since the intro is quite long I have added an option to skip it,
 this feature can be enabled with CUSTOM1=1.

 The demo can be downloaded here:
 ftp://ftp.amigascne.org/pub/amiga/Groups/Z/Zeus/ZEUS-Megademo.dms

 Enjoy the demo from HD.
