In my latest book, Atari Flashback: The Essential Companion:

 

we cover how to play 67 different first party Atari 2600 games, including Fun Facts, Tip & Tricks, and more. In addition, the first chapter covers Atari 2600 history, and the second chapter covers the current line-up of AtGames’ Atari Flashback products. As part of that second chapter, I tried to detail how the controls and switches mapped to that of the various consoles and handheld unit from AtGames. Unfortunately, as is par for the course with these things, some of those tables were cut for space considerations. Fortunately, I can reproduce them here. Enjoy!
