  This demo shows how to make direct programming of the Commodore Amiga hardware using C language.
  It is designed like in the early 90s.
  It consists of the following "old-school" effects:
  - color cycling animation (cpu and copper)
  - color gradients (copper)
  - font text scroll (blitter)
  - ambient sounds (paula)
  Compiled with SAS/C 6.58 and Includes release 40.13 (AmigaOS 3.1).
  Source code supplied for educational purpose only.



  Both .exe and .adf supplied.
  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)
  - Minimig V1.1 OCS, 68SEC000 / 7.09 MHz (Normal), 512 KB Chip, 0 KB Fast, Kickstart 1.3
  - Minimig V1.1 OCS, 68SEC000 / 7.09 MHz (Normal), 512 KB Chip, 512 KB Fast, Kickstart 1.3
  - Minimig V1.1 ECS, 68SEC000 / 49.63 MHz (Turbo), 1 MB Chip, 512 KB Fast, Kickstart 1.3



  Version history:
  - V1.0 20170517, first public release
  - V1.1 20170531: few fixes, now it works as designed



  Notes:
  - My Minimig configuration:
    Bootloader   BYQ100413
    FPGA core    FYQ100818
    ARM Firmware AYQ100818
  - The demo 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.
