VCS Game Maker

 Atari 2600

This online tool is a no-code environment designed to allow someone to create a game for Atari 2600 without knowing much about programming and without installing anything on their computer.

It uses Blockly to allow the user to implement the logic using blocks and then, behind the scenes, generate a Batari Basic source code, that is then be compiled using batari-basic-js in order to generate an Atari 2600 ROM, which is emulated using Javatari.
