Specific system information

File organization

Boom3 needs a file with the extension .boom3 to be placed in the roms\boom3 folder of your RetroBat installation.

The .boom3 must point to the subfolder and pak000.pk4 file:

Boom3 requires original .pk4 files from the Doom3 game and the Resurrection of Evil addon, you'll need the game data from a Doom3 installation patched to 1.3.1. Specifically, you'll need the following .pk4 files (base folder contains the original game data, d3xp contains the Resurrection of Evil game data):
