The Commodore BASIC 64 JS Online project, featured in the latest video by projectCD.Chronicles, is a browser-based emulator purpose-built for running and editing Commodore 64 BASIC code. This JavaScript-driven tool faithfully reproduces the experience of coding on the original hardware—without needing to install any software or launch a traditional emulator.
Commodore BASIC 64 JS Online is not a full C64 system emulator. Instead, it’s a near-perfect replica of the C64’s BASIC environment, focused on the language itself. Users can write, test, and save BASIC programs directly in their browser, all while using a classic-style screen editor that mimics the original look and feel. Compatibility with legacy BASIC commands sits at around 99%, offering a true-to-life development experience.
The emulator also supports PETSCII control characters, poke/peek operations, and even partial VIC-II functionality like sprite handling and text modes. Users can interact with programs using authentic keyboard input and screen manipulation, just as they would on real hardware. Load and save options are included, along with support for multiple BASIC file formats.
One of the standout features of BASIC64.JS is its accessibility. It runs on any modern browser and requires no installation, making it a perfect fit for retro programming enthusiasts, educators, or curious beginners. You can even toggle an optional extension to access enhanced BASIC commands that go beyond the original 64K limitations.
Whether you’re revisiting old code, writing a new BASIC game, or just exploring retro computing, Commodore BASIC 64 JS Online makes it easy to dive in. It’s a lightweight, powerful tribute to a timeless programming environment.
