WAD File

From SRB2 Wiki

WAD files are libraries of data files for any program that runs on the Doom Engine, such as Sonic Robo Blast 2. Stored in lumps, the data in a WAD file can have character data, maps, graphics, sound effects, and music. WAD files with all the main data of the game are IWADs, whereas WADs that work as patches are called PWADs.

Adding WAD files to the game

First of all, make sure that these WAD files are in the SRB2 directory. Then, add à la one of the following methods:

1. In the console, enter in ADDFILE FILENAME.WAD.
2. Use the SRB2 Launcher.
3. In Start Menu -> Run, type in SRB2DIRECTORYNAME\srb2win -file filename.wad You must enter in the directory name as the DOS command prompt would display it.
4. Add the ADDFILE FILENAME.WAD in autoexec.cfg in the SRB2 directory. This particular method will load that WAD file every time you run the game.

To remove a WAD file from the game, restart the game. Alternatively, if all the new data replaced just existing data, enter in ADDFILE SRB2.SRB to revert it. Note that you must use the former method to join a game online.

Creating and Editing WAD files

First of all, you need to create the necessary data files for that WAD as outlined in the respective tutorials. Then you use a WAD editor to add/extract/edit data into the WAD file. If you are adding a SOC file, create a lump called MAINCFG, and copy-paste the contents of the SOC file in said lump.

Downloading WAD files

Many WAD files can be downloaded from the Addons section of the SRB2 website, from the message board, from joining a netgame (these files are saved in the SRB2\Downloads folder), and from using a search engine.
