Albert Posted September 6, 2018 Share Posted September 6, 2018 You've surely seen QR Codes all over the place in the last decade. QR codes are a means of encoding information into a compact, square graphic that can be scanned (usually by cell phones these days) and decoded. Most often these codes are a link to a website, but they can be used to store any manner of information. Atari 2600 fan Seth Robinson recently embarked on the challenge of encoding Atari 2600 games as QR codes stored on paper cards, and then using a camera to decode the game and run it in an emulator. As QR codes can store about 3K of 8-bit data, a 2K Atari 2600 game can easily fit in a standard QR code. Larger 4K games can be encoded using two QR codes, one on each side of the card. You then have to flip the code to load the second half of the game. As a large percentage of Atari 2600 games are either 2K or 4K in size, this allows you to run quite a few games from QR codes. Seth used a Raspberry Pi and a Picamera and open source software to read the "PaperCart" Atari 2600 game cards he printed, and once decoded they are run in the RetroPie Atari 2600 emulator. For all the details about this PaperCart system system (including how to create your own), please visit Seth's Code Dojo page. 15 Quote Link to comment Share on other sites More sharing options...
