ECWolf requires base game data from the original games in order to play. For convienance this data is referred to as the IWAD since it is the equivalent to those files in Doom.

Supported data/IWADs

Below are the data sets supported by ECWolf. Each table contains the specific list of files needed as well as their md5 checksums. On OS X and Linux the md5sum tool can be used to generate a hash for your files. For Windows HashCheck or one of the many other tools can be used.

Wolfenstein 3D can be patched using the utility on this site.

Obtaining game data/IWADs

• Steam

Probably the easiest and cheapest way. On Windows ECWolf will even find the data for you automatically. Just be sure not to run the Spear mission packs through Steam since that will change your Spear of Destiny files. If you do so, then make sure you play the original game at least once through Steam to revert that change (or redownload).
