Course description

This course is a gentle introduction to the fundamentals of computer architecture and the 6502 assembly language. We will learn to create games for the Atari 2600 gaming console and understand how digital machines work from the inside. The minimal hardware setup of the Atari 2600 is an ideal sandbox for mastering low-level programming.

By the end of the course, you will gain practical skills in 6502 assembly programming, a deep understanding of the Atari 2600 architecture, and a completed personal game for the VCS, which we will develop together from scratch.

Required Tools

We will use a simple text editor, the DASM assembler, and the Stella emulator. All these tools are cross-platform, allowing you to work on Windows, macOS, or Linux.

Who this course is for

This is a fully self-contained course with no formal prerequisites. However, you will find it easier and more engaging if you are already familiar with basic programming concepts (conditions, loops, functions).

If you enjoy developing retro games and want to understand computer architecture and low-level code, this course is definitely for you!
