This tool allows you to patch the game binary of The Binding of Isaac to enable mods in online co-op play without the need to disable them beforehand.
Note: You will need to run the patch again each time the game updates.
While this patch allows starting online co-op with any mod installed, doing so can quickly cause desync issues. It often helps if all players have the same mods installed. Additionally, some mods may work even if others don't have them installed, but they might require special handling.
For further information, see the specific subdirectories (e.g., for External Item Descriptions).
This tool is intended for friends-only co-op play. While it probably works in other scenarios, those are not explicitly accounted for. I do not condone ruining other players' experiences in online matches.
Please use this tool responsibly and enjoy your enhanced co-op experience!
