GFA Basic Programming

GFA Basic is easily the most popular programming language for the Atari ST.

• GFA Basic Manual (ST Format Edition)

C Programming

C is the primary programming language used for professional Atari ST development.

• Makefile tutorial
  • A very useful guide to writing Makefiles.
• Object Oriented Programming in C
  • Explains how to implement object-oriented programming concepts in C.
  • The references at the bottom of the page are also very useful.

Assembly Programming

  • Some very interesting and useful Bugaboo debugger tips and tricks.
• Cycle counting in the Atari ST
• M68000 Programmer's Reference Manual

Cross compilation

This section contains resources for cross-compiling Atari ST software from other platforms. Developing on the Atari ST itself is often limited by its hardware capabilities and with cross-compilation, you can leverage more powerful development environments.

• M68k LVVM documentation
  • Resources for users of M68k LLVM toolchain.
• Platform Guide: Atari ST
  • A VBCC/VASM oriented guide.
• Thorsten Otto's m68k-atari-mint cross-tools page
  • A page full of resources for cross-compiling for the Atari ST using GCC.
• VBCC
  • A highly optimizing portable and retargetable ISO C compiler.
• GCC Docs

Github repositories

• ReservoirGods/GODLIB
  • An extensive C library by Resevoir Gods that provides many features that can be useful for game development.

Tools

• Compiler Explorer
  • Handy tool to see live compiler output asembly. Supports M68K GCC compilers and M68K assembly.
• Amiga & Atari Bitmap Converter
  • A command line tool to convert bitmap images into ready to use binary data.
• CycleSpitter
  • A cycle-accurate scanline splitter tool for Atari ST fullscreen (sync) programming.
