 This install applies to "Megademo 2"  1990 Vision.

 Requirements:
 -------------
 This install requires WHDLoad and DIC to be in the path.
 These programs can be found in the WHDLoad package.

 The installed game requires 0.5 MB ChipMem (+880k for Preload). 
 It can be quit by pressing Del (key can be changed with Tooltype "QuitKey=").

 - DMA wait in replayers fixed (x8)
 - Byte write to AudXVol fixed (x10)
 - SMC in part 1 fixed (skipped on 68000 machines)
 - Direct ROM jump to acknowledge IRQ fixed (x5)
 - Correct setup/restore of hardware registers (completely recoded!)
 - Bplcon0 colorbit fixes (x36)
 - Access fault in part 5 fixed ($5dff058->$dff058)
 - Keyboard handler added so quit works on 68000 machines
 - NewIcon  (created by me, if you have better icons freel free to send them)
 - Quit option (default key is 'F10')
 

 Here's another requested one. This time it's an installer for Vision's
 Megademo 2 which was requested by Karpow in the guestbook of www.whdload.de.
 The demo was released almost 20 years ago and is still nice to watch. 
 Nice code by TSM (who sadly passed away in 1996, RIP) as usual.
 Wasn't hard to fix as the code is rather clean. Just the usual problems
 (direct ROM jumps to acknowledge IRQ, almost non-existant startup/restore
 routines) made it crash on non 1.3/68000 machines.

 P.S.: Message to Karpow: installer for Deathstar's Megademo is 99% finished
       and will be released soon. :) 

 Have fun and enjoy yet another classic demo from HD now.

 Greetings to all in Scarab and Scoopex, the WHDLoad team and to Musashi5150 :)
 Extra greetings to the usual suspects on #amigascne, see you all at
 Breakpoint 2010! :)
