How the Nintendo Entertainment System lives on in open source - Game Bytes

Welcome to the July edition of Game Bytes, a monthly series focused on the game developer community. This month, we take a look at the legacy of the Nintendo Entertainment System (NES) in open source.

The NES was released 35 years ago today. While official NES games haven’t been released in over 20 years, a “homebrew” scene exists where developers are still creating NES games (playable on the original hardware or on emulators) in the original 6502 Assembly Language.

Whether you grew up playing NES games, or your parents did, you’re bound to find something of interest—either in the gameplay or in the code—for some of these games below.

Open source homebrew NES games

Super Tilt Bro

Not much is known about why our hero is “Falling” from the sky, but they must collect as many coins as possible while avoiding all platforms. This was @tragicmuffin’s first time creating a game from scratch and working with Assembly.

Sprilo

You might not know 6502 Assembly Language, but if you have some experience with C++ then the SuperTux team are looking for people to assist with continuing development of the classic platform game. Contribute to the core gameplay or contribute content through the integrated level editor.

Js13kgames starts next month

The seventh annual js13kgames–a JavaScript coding competition for HTML5 game developers–kicks off next month. If you don’t know 6502 Assembly Language or C++, but are comfortable around HTML/CSS/JS, @end3r’s month-long game jam to create a JavaScript game in less than 13 kilobytes might be for you!
