 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 (+1.1 MB for preload).
 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD (real files!)
 - DMA and interrupt settings fixed
 - Interrupt acknowledge fixed for 68040/60
 - CPU dependent timing fixed
 - DMA wait in replayer fixed (x9)
 - Byte write to volume register in replayer fixed (x9)
 - ButtonWait support for loader part
 - Decrunchers (Tetra Pack 2.2) relocated to fast memory
 - NewIcon (created by me)
 - Source code included as usual
 - Quit option that works on 68000 machines (default key is 'F10')
 
 I started to patch this demo back in June and had most of it finished
 after some days. There were some minor problems in the skyline
 (timing) and the starwars scroller part which is why I didn't release it
 until now. Today I fixed these problems and finished the patch.
 I always liked this demo, classic mega demo style with some nice ideas
 such as the skyline part, rather simple code but such a nice idea!
 The code is quite OK, in one part the coder used a wrong hardware
 register to enable the interrupts (DMACON instead of INTENA), it
 only worked correctly by coincidence. Other than that there were
 no real major problems. All parts were crunched with Tetra Pack 2.2
 which is basically nothing more than a ByteKiller clone with an
 additional RLE pass. I have relocated the decruncher to fast memory
 to speed up decrunching.
 If you want to listen to the loader tune you can use the ButtonWait
 tooltype, you will then have to press either mouse button to quit
 the loader part.


 Enjoy the demo from HD.
