Seth explains the process in a second, more technical video. He builds cartridges using basic materials like stone and dirt, each block standing in for a certain binary value. He can use those blocks to assemble the code for games.


After that? It’s the long process of using the allocated memory to draw the sprites. The data is occasionally drawn into the wrong spot on the screen but given the fact that this is an emulator that used Minecraft blocks that’s only a small setback.

Seth has shared the world file for people who want to check it out for themselves, as well as an editor to help folks load in their own ROMs. So, if you happen that have Atari ROMs laying about and are sick of seeing them run at normal speed, boot them up in Minecraft and sit down for the longer game of Pac-Man you’ll ever play.
