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

Here is a recording: https://www.youtube.com/watch?v=pp73ycqGzBE

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)

- Real hardware, various systems with different cpu and chipset

Version history:

- V1.2 20220313, 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 PlanetR_V1_?_YYYYMMDD.c p61.o
