  The intro was coded by Massimiliano "AlienTech" Scarano for the Amiga demo
group VOID
  and presented at Revision 2020, where it was ranked 10th at the "Amiga Demo"
competition.
  Here is the official recording:

  This intro shows how to make direct programming of the Commodore Amiga
hardware using a mix of C and Assembly.
  It is designed like in the late 80s / early 90s.
  It consists of the following "old-school" effects:
  - bounce scroller (blitter)
  - color bars (copper)
  - MOD music (paula)
  The Player Playroutine P6112 assembled with PhxAss V4.40.
  Compiled with SAS/C 6.58 and Includes release 40.13 (AmigaOS 3.1).
  Source code supplied for educational purpose only.



  It should work on any PAL Amiga, with a Motorola 68000 cpu and OCS chipset,
  and whatever OS (Kickstart + Workbench) version.
  Tested OK:
  - Amiga Forever 2013 (WinUAE, cycle exact emulation)
  - Amiga Forever 7 (WinUAE, cycle exact emulation)



  Version history:
  - V1.0 20200202, first public release



  Notes:
  - The intro should run at constant full frame rate (50 Hz),
    the screen is updated every frame.
  - Commodore Includes 40.13 were distributed with SAS/C 6.51.
  - RAW gfx format consists of all rows of the 1st bitplane, followed by all
rows of the 2nd bitplane and so on.
  - Build with:
    > phxass p61.s
    > sc link Yip_cover_V1_?_YYYYMMDD.c p61.o
