 This install requires WHDLoad and RawDIC to be in the path.

 It can be quit by pressing F10 (key can be changed with Tooltype "QuitKey=").


 Features:
 ---------
 - Full load from HD (real files!)
 - ColdCapture patching disabled
 - Blitter waits added (x41, only enabled on 68010+ machines)
 - Blitter wait patches can be forced on 68000 machines with CUSTOM1
 - Self-modifying code fixed
 - All OS stuff patched
 - CPU dependent delays fixed 
 - All decrunchers (TetraPack 2.2) relocated to fast memory
 - Bplcon0 color bit fixes (x4)
 - DMA wait in replayer fixed (x9)
 - Byte write to volume register in replayer fixed (x6)
 - Interrupts fixed
 - DMA settings fixed

 Here's the patch for Humanoid's Megademo which is still entertaining
 to watch, it's actually another one of my old favorite demos.
 Really nice parts, good graphics and music here. Creating the
 patch took quite some time even though the code is rather good.
 The plasma code is nicely optimised and uses all registers including
 a7 in the innerloop. I had level 2 interrupts enabled for checking
 the quit key which resulted in graphics corruption in the plasma.
 Took me a little while to find the reason, this kinda annoyed me
 because I had disabled interrupts already because I noticed that
 a7 was used in the innerloop but forgot about the level 2 interrupt.
 Anyway, after about an hour of checking the code and trying various things
 I finally fixed the problem. During that hour I created quite a few
 interesting incarnations of the plasma part. :)
 Other than that there was some self-modifying code used which I have fixed,
 the only exception here is the "Evolution" part, there's such an amount of
 SMC used that I decided to simply disable the cache, I may fix all the SMC
 in a later version of the patch. Some blitter waits had to be added too,
 these patches are only installed on machines with a 68010+ CPU, to force
 the blitter waits on 68000 machines you can use CUSTOM1=1.

 Enjoy this really nice classic from HD. You can download it here:
