Undertale File Info
This Page Contains Info on How To Edit The Files Of Undertale.
To edit the Undertale files you need to go to your Undertale folder (com.tobyfox.undertale), to do this on
OS X, you must open finder, then go to the top of your screen where it says "Go", then click "Go To Folder"
and type in ~/Library, from there go to Application Support, and look for your Undertale folder (com.tobyfox.undertale)
and go to "file0", there there is 549 lines, each with a number representing something, except the first
line, which states your character's name. You can change any of these, but I would recommend to only change
something if you know what it does. Once you have changed something, close, and reopen the game for
it to work. Some key lines you will most likely want to know are lines 1, 2, 3, 4, 11, 13, 29, 30, 36, 548,
and 549. The following list explains what each of those lines does, you can also find this information in the
first link to the right. The other links will be helpful for learning this as well.
