JS GameBoy Emulator

GameBoy emulator coded in JavaScript for browsers. You can see it working on http://gb.alexaladren.net

Usage

  • You can play it directly on http://gb.alexaladren.net
  • You can download this repository and open index.html with any browser

Code

The JS code is divided in 3 files:

  • emulator.js handles the interaction with the browser and the player itself. It contains code for loading ROMs, receiving input and save games.
  • GameBoy.js simulates the 'motherboard' of the GameBoy, including memory addressing, rendering, time control, audio, etc.
  • Z80.js emulates the Z80 processor used in GameBoy, the instruction set and registers. It is coded in ASM.js, a subset of JavaScript that allows browsers to 'compile' the JS code for faster processing
