CHIP-8 is a small virtual machine known for its compact programs and games. I implemented an interpreter in JavaScript to explore how its instructions execute.
Interpret a machine one step at a time
The interesting part is the relationship between the machine’s state and the instruction being processed. Small operations combine to produce drawing, input handling, and the behaviour of a program.
Watch the result and follow the code
The demo shows the interpreter running in the browser. The screenshot uses Space Invaders as a visual example of the result.
The repository is a starting point for studying the interpreter’s structure and how its instructions connect to the display and controls.
