Have you ever missed playing video games from your childhood?

I grew up with the Famicom and Game Boy Advance. Games like Pokémon, Mario Kart, Dragon Ball, and many more are fond memories.

EmulatorJS is a web-based multi-system emulator that runs in the browser. It can emulate many classic consoles like NES, SNES, Game Boy, GBA, and more.

Setting Up EmulatorJS Locally

Prerequisites

• Install Node.js from the official website (https://nodejs.org/).

Download the Source Code

Open a terminal and run:

git clone https://github.com/EmulatorJS/EmulatorJS.git

If Gits not installed, you can download the ZIP archive from GitHub and extract it.

Install Dependencies

Navigate to the project folder and install dependencies:

cd EmulatorJS
npm install

After installation, a node_modules folder will appear.

Optional: Download Emulator Cores for Offline Use

For offline usage, download the required emulator cores from:

• https://cdn.emulatorjs.org/nightly/data/cores

For example, to play GBA games, search for "gba" and download mgba-legacy-wasm.data (for older browsers) or mgba-wasm.data (for modern Chrome). Place the downloaded file in:

EmulatorJS/data/cores

Running EmulatorJS

Start the server with:

npm run start

Then open the provided URL in a browser. Drag and drop a ROM file (e.g., a .gba file) onto the page to start playing.

Features

• Save and load game states.
• Supports multiple console cores.
• Customizable controls.

Enjoy your classic games!
