This directory contains sample programs for the cc65 compiler.

Below is a short description for each of the programs, together with a list
of the supported platforms.

Please note:

  * The supplied makefile needs GNU make. It works out of the box on Linux and
    similar systems. If you're using Windows, then consider installing Cygwin
    or MSys2.

  * The makefile specifies the C64 as the default target system because all
    but three of the programs run on that platform. When compiling for another
    system, you will have to change the line that specifies the target system
    at the top of the makefile, specify the system with SYS=<target> on the
    make command line, or set a SYS environment variable.


List of supplied sample programs:

Platforms:      The program does depend on conio and dio (direct disk i/o),
                so it currently does compile for only the Atari and Apple ][
                machines.

Name:           fire
Description:    Another graphics demo written by groepaz/hitmen.
Platforms:      The program currently is running on only the C64, but should
                be portable to the C128 and CBM510 (and maybe more machines).

Description:    A mandelbrot demo using integer arithmetic. The demo was
                written by groepaz/hitmen, and converted to cc65 using TGI
                graphics by Stephan Haubenthal.
Platforms:      Runs on all platforms that have TGI support:
                Apple ][, Atari, C64, C128, Oric Atmos and Telestrat, GEOS,
