  Coded by Massimiliano "AlienTech" Scarano for the Amiga demo group VOID.



  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:
  - sine scroller (blitter)
  - 2D stars (hardware sprites)
  - 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.



  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 20180225, first public release



  Notes:
  - My Minimig configuration:
    Bootloader   BYQ100413
    FPGA core    FSB150520
    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.
  - Build with:
    > phxass p61.s
    > sc link HelloVOID_V1_?_YYYYMMDD.c p61.o
  - Run the following on a very fast Amiga to enjoy a 1 pixel sine scroller:
    > HelloVOID.exe turbo

  Many thanks to Esau for his music.
