The Binding of Isaac: Rebirth: Using MODs Online
Short answer
Hello there guys, so with a little of search i discovered how to use mods in online, i will show you step by step in this guide.
Steam Community guide by Slayer_of_2012.
Installing the modded .exe to allow mods online
First of all i would like to give a huuuuuge thanks and a hug to the creator of this patch, without it nothing of it would be possible, if anyone knows his Steam please comment below so i can give him the credits but anyways, his github is xADDBx
First of all you guys need to download this thing here from his github:
https://github.com/xADDBx/Isaac-Online-Modded
After you have download it, you need to open it and patch your isaac-ng.exe file, the default folder should be (C:/Program Files (x86)/Steam/steamapps/common/The Binding of Isaac Rebirth\isaac-ng.exe)
With the game's .exe patched it will allow you to load mods normally in the menu and getting online without asking you to turn mods off and restarting the game to be able to acess the online option.
You need to reapply the patch everytime the games gets updated (currently the game is at 1.9.7.10)
Note: Your windows or antivirus will probably gives you a heads up for the file being "a trojan", don't worry about that is a false positive, i will post xADDBx it's own words about it below:
Considerations
It's important to say that allowing some mods will cause desync, but the author on github said that if all players have the same mods installed and enabled that won't happen (meaning this is awesome to play along with friends)
But some mods don't cause desync at all, even if you are the only person with that mod installed (for example: EID External Item Descriptions) this one in fact is the one that made me search the entire internet to find a method of how to use mods in online, cause i can't really play without it.
Note: I didn't tested my other mods cause i still didn't catch up with the few friends i have to test a run with everyone with the same mods installed.
Note 2: I didn't tested and didn't heard a word about class mods to work, but i highly doubt this would work even if everyone has for example (Class mod Mei installed) but i could be wrong, if you guys have the time and the team to test it and works, let me know in the comments.
External Item Descriptions
In order for EID works correctly you need to change two values from false to true in the main.lua of the mod by default it should be located at
(C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth\mods\external item descriptions_836319872)
You can manually change the following values in the main.lua of the mod to true:
Mods i tested with randoms and didn't caused desync
