  The intro was coded by Massimiliano "AlienTech" Scarano for the Amiga demo group VOID
  and presented at Outline 2021, where it was ranked 11th at the "combined demo/intro" competition.
  Here is a recording: https://www.youtube.com/watch?v=ZP3hQ_KBUqs

  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.
  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 600
  - Amiga 1200 - 020 - 4 MB Fast
  - Amiga 1200 - 030



  Version history:
  - V1.0 20210501, 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 Birthtro36_V1_?_YYYYMMDD.c p61.o
