 This install applies to "Megademo 2"  1988 Vortex 42.

 Requirements:
 -------------
 This install requires WHDLoad and RawDIC 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 (+0.7 MB OtherMem for preload).
 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD (real files!)
 - OS stuff emulated (SendIO, Forbid, Permit etc.)
 - Blitter waits added (x35)
 - Self-modifying code fixed
 - DMA wait in replayer fixed (x7)
 - Byte write to volume register fixed (x8)
 - Interrupt and DMA settings fixed
 - Byte write to color register fixed (x3)
 - Bplcon0 color bit fixes (x4)
 - ROM reads fixed (x3)
 - Random generator fixed
 - Timing fixed
 - CPU dependent delays fixed (x6)
 - ButtonWait support for loader part added
 - Interrupts fixed
 - NewIcon (created by me)
 - Source code included as usual
 - Quit option that works on 68000 machines (default key is 'F10')

 Here's the patch for the second Megademo by Vortex 42. It was requested
 some days ago and I spent about 10 hours the last 2 days creating it.
 The bootblock intro is not supported (yet) as it uses quite some ugly
 hacks in the code and also OS routines for drawing etc. I may support
 it in a later version of this patch but don't hold your breath, it's quite
 some work for not much benefit!

 Speaking of OS routines, in part 2 mathffp library was used to calculate
 the data for deforming the picture, I first tried to emulate it but wasn't
 successful and after a while I simply decided to include the precaluclated
 picture data in the patch. This might also be changed in a later version of
 the patch but yet again, don't hold your breath!

 Other than that there were a lot of ROM accesses to fix, these were mainly
 used to generate random data for starfields and to set interrupts which made
 the demo crash on anything else than Kickstart 1.2 machines. A lot of
 blitter waits and other fixes had to be applied as well which took a fair
 amount of time.
 
 I have added ButtonWait support for the loader part, use it if you want
 to listen to the loader tune. If enabled the parts won't start until either
 mouse button has been pressed.


 Ennjoy another classic from HD.
