Deltamod

Deltamod is an 1-click mod manager for all Deltarune versions and select other games.

It includes the following functionality:

• Support for both paid and free Deltarune versions, UNDERTALE and Undertale Yellow, with more games to come!

• Copies Deltarune installation one-time and performs all operations, including backup, on it

• New prepackaged mod format support (Deltamod modpack zip) to make installing mods easier.

• Multiple mod support, powered by GM3P. DEVICE_FUSION support was added recently.

• Currently supports GameBanana 1-click protocol!

• Browse GameBanana mods using the new Mod Shop UI.

• Supports integration with Steam using symlinking.

• Includes tools to create modpack files.

For multiple mod support, Deltamod uses GM3P under the hood, with the option to use DEVICE_FUSION (in beta).

Deltamod is available for Windows, with support to Linux coming soon.
