Further Reading#

This book aims to be the accessible path into the VCS — the explanation you read first. For exhaustive, bit-level reference, and for the wider community that keeps this machine alive, these are the sources to reach for next.

The Stella Programmer’s Guide#

The definitive low-level reference: Atari’s own internal manual for the TIA and RIOT, written by Steve Wright in 1979 (“Stella” was the VCS’s development codename). It is the primary source behind the hardware behavior described throughout this book — and where to turn when you need the things a how-to deliberately leaves out: the complete register address-summary table, the exact AUDC waveform values, the numeric color/luminance chart, and PAL/SECAM conversion details.

• Read it at the Internet Archive (a durable, freely accessible copy), or via the long-standing atarihq.com mirror.

The guide is a copyrighted Atari document; this book links to it rather than redistributing a copy. Where a page here says “see the Stella guide,” it means the section of that manual covering the same register.

Learning the machine#

• Pikuma — “Atari 2600 Assembly” — Gustavo Pezzi’s course; the structured, from-first-principles approach this repository follows.
• 8bitworkshop — Steve Hugg’s in-browser IDE (edit 6502 assembly and watch the beam draw in real time) and the companion book Making Games for the Atari 2600. The fastest way to experiment without a local toolchain.
• AtariAge — the homebrew community’s hub: forums where current VCS developers gather, plus classic tutorial series (Andrew Davie’s “Programming for Newbies” among them). The place to ask questions and see active projects.

6502 reference#

• masswerk 6502 Instruction Set — a clean opcode-and-cycle reference for the 6502 basics the VCS’s CPU shares.
