Classic video games might look primitive by today’s standards, but the addictive gameplay of Breakout or Pac-Man remains fun no matter what decade you were born in. Keeping the relevant hardware running becomes harder as the years pile up however, so when [Michal Zalewski] decided to introduce his kids to classic video games, he didn’t dig up his old game consoles. Instead, he decided to recreate several games from scratch using the bare minimum amount of hardware needed.

The first project is a copy of Snake, the arcade classic that millennials will recognize from their Nokia phones. [Michal] made an initial version using an ATmega328P with an 8×8 LED matrix as a display, but quickly upgraded the hardware to a 16×16 display powered by an ATmega644, and added an LED seven-segment display to show the score. All parts are simply soldered onto a piece of prototyping board, with no need for any custom PCBs or enclosures.

Game #2 is a side-scrolling space shooter called Dino in Space. This game runs on an ATmega1284 and uses a 4×20 character text display, allowing simple graphics as well as an on-screen score counter. Similar hardware, although with a 128×64 graphic OLED screen, powered game #3, a Breakout/Arkanoid clone called Blockbuster 7000.

[Michal]’s blog post is filled with interesting tips for real-life game programming. For example, a true random number generator creates a rather odd-looking bunch of asteroids in space – tweaking the distribution to make it a bit more uniform greatly enhances the game’s playability. Source files for all games are available on [Michal]’s website, and include a description of the exact hardware setup needed for each game.

Recreating Snake on custom hardware is sort of a rite of passage for microcontroller hackers, as you can see in  many impressive projects. Breakout-style games can also be implemented on various hardware platforms, including analog oscilloscopes.
