 This install applies to "Megademo"  1988 North Star.

 Requirements:
 -------------
 This install requires WHDLoad to be in the path.
 To install from a different drive than DF0: select installation mode Expert.

 The installed demo requires 0.5 MB ChipMem (+1.1 MB OtherMem for preload).
 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD
 - OS stuff patched (AllocMem, FreeMem, file loading, relocation etc.)
 - Byte write to CopJmp1 fixed (x5)
 - Bplcon0 color bit fixes (x19)
 - Self-modifying code fixed
 - Write to HTOTAL ($dff1c0) fixed
 - DMA wait in replayer fixed (x5)
 - Wrong memory allocation checks fixed (x2)
 - Modulo bugs fixed (x2)
 - Timing fixed
 - CPU dependent delay fixed
 - Bugs in scrolling routines fixed (x3)
 - Reset at end of demo patched to quit back to DOS
 - Copperlist bugs fixed
 - Interrupt fixed
 - NewIcon (created by me)
 - Source code included as usual
 - Quit option that works on 68000 machines (default key is 'F10')

 This was fun to do, yet another classic and still entertaining
 demo has now been patched. Worth mentioning is that all parts use
 standard relocatable executables and allocate the needed memory
 using AllocMem, so (almost) no absolute addresses were used, definitely not
 common for a 1988 demo! Restoring the system copperlist was done assuming
 the default copperlist is at address $22f8, this only worked correctly
 on Kickstart 1.2, on all other Kickstarts invalid copperlists were
 restored resulting in a lot of graphics trash at the end of each part.
 Fixing this wasn't much of a problem though.

 There were some glitches with the scrollers in some of Atom's parts
 that kept me busy for a while but I found a good enough workaround I hope.
 These problems only occured on fast machines for some reason.

 
 All files in the "data" directory can be packed with any of the crunchers
 supported by WHDLoad (FImp, ProPack etc.).

 Enjoy yet another classic demo from HD. This patch is dedicated to the
 memory of Atom!
