Another World JS
This is a Javascript (HTML5) port of the game Another World designed by Eric Chahi.
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.
Features
This port has a few extra features, besides the ability to run in a browser :
- switch between Amiga and EGA palettes
- switch between the original 320x200 and 640x400 resolutions
- rewind game play
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
Archive: ootwdemo.zip
Zip file size: 531072 bytes, number of entries: 14
