Hey everyone. If you're like me, and you want to play Repentance+ with mods because of the new item changes, this guide is for you.



The steps are as follows:

1. First, the new mods location is in "Documents/My Games/Binding of Isaac Repentance+". Keep note of this.
   
2. Next, you're going to find the old mods location folder. It should be in "\steamapps\common\The Binding of Isaac Rebirth/mods". We're going to drag everything from this folder into the new "mods" folder.
   
3. You'll need to check and make sure which mods require RGON so that you can delete them from the new mods folder. Make sure to do this as it will either not work or create issues within the game such as crashing.
   
4. Congrats you've modded Repentance+ !!!!

But we're not done yet.

As of right now, when subscribing or unsubscribing from workshop mods, they will not be installed in either the old mods folder or the new one unless Repentance+ is not installed. There are two methods to work around this. (Thanks for the mod author of EID, Wofsauge, for making me aware of the first method).

1. Install/Uninstall Any mods from the workshop that you want in Repentance+ (while making sure that no mod that needs RGON is included)
   
2. Uninstall Repentance+ and start Repentance. This populates the old mods folder with the newly acquired/removed/updated mods.
   
3. Reinstall Repentance+, copy everything from the old mods folder in the new one
   
4. Profit???

1. The workshop folder is located in "steamapps/workshop/content/250900/" We need this in order to find the mods that we have subscribed to or updated. In doing so, you'll find a whole lot of folders named after a bunch of numbers. These are the mod files steam ID that lets us identify which mod is which. If you're not sure what the ID number of the mod your looking for is, go to the mods page. At the top, a link should be visible, and an id="number" identifying which mod it is. Ex. "id=836319872" or "836319872" is the EID mod.
   
2. Next, you'll want to create a folder for that mod. So, still using EID as an example, I would create a folder named "external item descriptions_836319872" (the original name of the mod folder inside the old mods folder) and place it inside "My Games/Binding of Isaac Repentance+/mods." This will update/add the mod into the game.
   
3. Profit???

This method is more painful but maybe this method will help those who aren't able to get the first one to work. These are the only two methods that I am aware of. If there is a much better way, please.... Please tell me. "Jokes" aside, hopefully this lets yall play Rep+ with mods. I personally have a curated list of QOL mods that work perfectly with Rep+. Some, such as "unintrusive pause menu" will crash the game on launch unfortunately.

Edit: Haven't tested it myself but u/abyr-valg says:

Alternative method of downloading mods is via DepotDownloader.

https://github.com/SteamRE/DepotDownloader

For example, if you want to download External Item Descriptions:

.\DepotDownloader.exe -app 250900 -pubfile 836319872 -username {Steam-login} -password {Steam-password} -remember-password


u/PabloTz01:

If someone is struggling with installing mods on a Steam Deck (linux) you have to follow the firsts steps BUT the folder where you need to put your mods it's in the proton directory.

Try looking under ~/snap/steam/common/.local/share/Steam/steamapps/compatdata/<appId>/pfx/dosdevices/c:/users/steamuser/Documents/My Games/Binding of Isaac Repentance+/mods

Appid for rebirth is "250900"

Happy Modding!
