What is a J2B file?

A J2B file is an audio module used by Jazz Jackrabbit 2, a video game developed by Epic Games. It contains a song played in the game. Jazz Jackrabbit 2 uses a version of the Galaxy Music System, an audio engine used by several Epic games, to play J2B files.

More Information

Developer Carlo Vogelsang created the Galaxy Music System, also called the Galaxy Sound System, while contracted with Epic Games. Epic used Galaxy in Unreal, the first version of Unreal Tournament, and other video games, including Jazz Jackrabbit 2.

The version of Galaxy used in Jazz Jackrabbit 2 plays audio modules saved as J2B files. These J2B files are .S3M or .IT files that have been encrypted and optimized specifically for use with Galaxy.
