Binding of Undertale+Deltarune (Replacer Version)

ATTENTION: After installing: Open your game WITHOUT ANY RUNS, RESTART IT, then open it and it should work fine, but this is VERY IMPORTANT!

ATTENTION: The modding API is VERY unstable with XML mods now. This mod might crash or have issues, and will crash if you disable it while doing a modded character run. It will also not work properly unless you restart, since the game does NOT re-apply XML files when you enable the mod via mod menu. (wich this mod has a lot of) It only reapplies them if you re-start the game wich is why it's really important to restart after booting up once (preferably without any runs active) I really wish I could fix this, but this is an inherent problem with Isaac's load order.

This mod replaces characters, music, end bosses and floors with Undertale/Deltarune content! Enjoy!

-Mod's Subreddit

- For now, this is a mod that changes graphics, characters, and starting items! Altough, if new item ideas arise, they might be added. Accepting suggestions!

- Mettaton, Ralsei(2) and Berdly have custom items.

- This mod changes the item's visuals to be Undertale themed. If you want to know what they do before picking them up, I suggest installing this mod: External item Descriptions.

- If your character's costumes keep dissapearing or are obscured by Isaac's costumes, I suggest this mod: Old Wardrobe!

-This is incompatible with mods that change players.xml, backdrops.xml, etc.



Q: The menu changed, but the game didn't!
A: Nicalis screwed something with XML modding in the Repentance update. To fix this, when you first install the mod, open the game and restart it. This should make the game read XMLs correctly.

Q: I can't open my game/My game and runs crash!
A: Step 1:
On Windows: Navigate into \Documents\my games\Binding of Isaac Repentance
On Mac: Navigate into /Library/Application Support/Binding of Isaac Repentance
Step 2: Open options.ini, find and make EnableMods=0
Step 3: The game should now open normally. You can either go to the mod screen in-game, enable mods and then disable each one individually, if you wish. Restart the game once.
Optional: If you wish, unsubscribe then re-subscribe to refresh the mod. Make sure to open and restart the game once.
Make sure to not uninstall the mod while you have a modded run enabled, it will result in the same error. Uninstall only when you don't have any runs.

Q: I can't unlock anything!
