Basic64 JS, the Commodore 64 Basic Emulator

Welcome to the Basic-64/js wiki!

(Short: BJ64)

BJ64 is a javascript implementation of Commodore64 basic, that is intended to run in the browser. It includes the full screen basic editor.

Note: This is NOT a Commodore 64 (full) emulator. What is the difference? Check Here.

For starting programming in Commodore basic, there are many resources online. On that I can recommend is this one: Commodore Basic on the C64 Wiki

Goals

• Runs in any (modern*) browser
• No need to install
• Optimized for editing basic programs
• Screen editor emulation. To get that look-and-feel from a Commodore computer.
• Vic2 emulation (poke/peek); Sprites, Text mode, full PETSCII character set
• PETSCII control characters. Example: clear/home. Colors: White, Black, Red, ...
• Tries to be 99% basic compatible
• Added modern features
• Classic look and feel editing environment
• Storage. Save / Load your programs to browser storage.

Why?

Why did I create this implementation of commodore 64 basic?

Website

Mostly because I wanted a website where I could just do cool C64 basic programming, without installing an emulator (such as VICE).

Keyboard

Also, I find Emulators, as fantastic as they are, lacking when it comes to keyboard help. And especially on old computers like the commodore 64, keyboard layout / help, is crucial. Basic coding needs many PETSCII characters, and looking them up in a table again and again is tedious.

Note: I found this out the hard way, when I tried to type in a listing from "Commodore Info" magazine, and found I am constantly trying to figure out which key combo to use.

Text files

Also I want to be able to import / export / C64 basic programs as text files. ".PRG" files are great, but impossible to edit in a modern editor.

Share

I also wanted a way to share commodore 64 basic programs in an easy way, for example on facebook or twitter.
