Ways to install:

• Mod manager: The mod can be found on both G3M & Deltamod.

• Run the installer: Download installer_difficulty_both, then run the installer for your OS (.cmd for windows).

• DeltaPatcher: Not recommended. However, you could download the data-pack and apply each .delta file manually.

Patching fails?

First make sure to verify integrity of your game files on Steam (right click Deltarune > Properties > Installed Files > Verify integrity of game files).

If you're using a non-Steam version of the game/demo, I can't guarantee the patching will succeed, as the patch is intended for the latest version from steam. The mod's installation script *might *work for you instead, as it does not require the data files to be an exact match.

Also note that if you're installing multiple mods, there's a chance they may not work together. I can look into these conflicts, but I can't promise I'll always be able to find a fix.

Can't merge with the 60 fps mod (or other)?

On G3M, go to Settings>Game>Patching/Merging and tick both boxes.

On Deltamod, merging of these two mods is currently impossible. ~11th Sept '26
