 I had started the patch for this music disk back in 2015 already, but did
 not finish the required code for emulating certain graphics library functions.
 I now started the patch from scratch (as I actually did not remember that
 I already started it some years ago) and added all the required code to
 emulate the OS functions.
 The demo uses ScrollRaster and RectFill graphics library functions to
 draw the analysers. Creating the emulation code took quite a while, I needed
 about 8 hours total to create all patch code, most of that time was spent
 creating the graphics library emulation code.

 The latest version of the source for this patch can be found on
 my Github: https://github.com/MK1Roxxor/WHDLoad_Patches/blob/master/Demos/Vega_MusicDisk3_WHD.s

 Enjoy the music disk from HD.
