How to install the mod

Trouble shooting

If you still encounter issues with the installation process, please try to fix common issues using the Interactive FAQ.

Installation guides

Steam (AB+, Repentance or Repentance+)

1. Open the Steam Workshop page of the mod: https://steamcommunity.com/sharedfiles/filedetails/?id=836319872
2. Press the green "Subscribe" button
3. Start the game. This will install the mod automatically and will keep it up-to-date.

If you want to install the mod manually, follow the guide below for the "cracked" installation instructions, and use the latest(1.7.9b.J835) mod version. Manually installing the mod will not keep the mod up-to-date, so use at own risk.

Epic Games / GOG / Cracked

1. Download the correct version of the mod.

   • Epic Games or GOG (1.7.8a): https://github.com/wofsauge/External-Item-Descriptions/releases/tag/V4.42
   • Cracked:
     • make sure you have the latest version of the game installed. Its Binding of Isaac: Repentance v1.7.9b.J835
     • you can find the game version, by looking into the log.txt file found here: C:\Users\[username]\Documents\My Games\Binding of Isaac Repentance\ the line in the file looks like this: [INFO] - Binding of Isaac: Repentance v1.7.9b.J835
     • If you want to have EID for older game versions, you can get them here: latest(1.7.9b.J835) 1.7.9a 1.7.9 1.7.8a
     • If you are on version 1.7.9c, you downloaded a version of the game that got removed by the devs themselfs, because it destroyed half of the modding API and a lot of mods. To fix that, download another version of the game, preferably 1.7.9b.J835 (latest)

2. Extract the content of the "external.item.descriptions.zip" file

3. Put the folder "external item descriptions" into your mods folder like this:

   • Repentance: ..\The Binding of Isaac Rebirth\mods\external item descriptions\
   • Afterbirth+: ..\Documents\My Games\Binding of Isaac Afterbirth+ Mods\external item descriptions\

   The folder should now look like shown on the screenshot.

   Make sure that when extracting the .zip file, you only have ONE "external item descriptions" folder, not two inside one another. Otherwise, the mod will not work!!!

4. Start the game

Rebirth & Afterbirth

Rebirth and Afterbirth have no modding API, which prevents us from executing code inside the game. Therefore these game versions use a special version of the mod that works by replacing game assets.

1. Download the version you need:
   • Rebirth (no DLCs): MediaFire
   • Afterbirth (first DLC): ModdingOfIsaac.com - MediaFire mirror
2. Extract the .zip file
3. put the content from the .zip file into the "resources" folder of the game, so that, for example, the "gfx" folder is directly inside the resources folder

iOS (Rebirth)

Credits to syfex for documenting

The iOS version currently uses Rebirth, which has no modding API and therefore does not support LUA mods. nontheless you can mod this version by the Resource modding method:

1. Download the Rebirth version (no DLCs) of the mod: MediaFire
2. Optain the .ipa file of the game and extract it with WinRar or 7-Zip
3. Navigate into /payload/data/resources
4. Put the content from the mod's .zip file into the "resources" folder of the game, so that, for example, the "gfx" folder is directly inside the resources folder
5. Install the modified .ipa file with sideloadly and your done
