Another World JS

This is a fork of another_js written by @cyxx which adds the following features:

• sound & music support (using Audio Worklet)
• touch controls
• fullscreen support
• fixes pause bug: resuming would skip time elapsed during pause
• webpack build

This is a Javascript (HTML5) port of the game Another World designed by Eric Chahi with the following features:

• switch between Amiga and EGA palettes
• switch between the original 320x200 and 640x400 resolutions
• rewind game play

Demo

The DOS demo version of the game can be played at warpdesign.github.io/another_js

Internals

This port behaves the same as the original executable and interprets the game bytecode.

The implementation of the 26 opcodes can be found here.

Data files

As the game data files are not freely distributable, you will need to extract and convert your original files.

This can be done using extract.py. The script takes datafiles as input and outputs a .js file to be included in the main .html page.

For example, the DOS demo data files can be converted with these commands :

$ zipinfo ootwdemo.zip
