(UPDATED) How to Modify Undertale and Deltarune For Dummies in 2025

use the editors below to modify your saves.

UPDATE AS OF 2/16/2025:

Thank you all for using my guide for over 3 years. it was a pleasure to help you all modify your saves.

Unfortunately, i cannot keep updating this guide but for a very good reason..
i'm lazy.. and busy gaming.. and dealing with life.. etc..

Fortunately for you all, some very talented people have made save editors for both deltarune and undertale that i will direct you to use instead of my method, as it is much simpler and easier to do than my method.

until we meet again in another timeline, human..
