If you turn blue, you've done it! Here is a list of all that debug mode does, and it can vary based on the current state of the player. You'll select a box, and now simply type "01". To do this, in the same top left box in your Hex Editor, paste in this number: 007748C4. Now, you'll have to enable debug mode in order to get unstuck from certain spots when porting to rooms (Since you aren't really meant to enter them, y'know?). Keep this folder open, because you'll need these files later. Scroll down, and there should be a folder called "UNDERTALE". It might default to AppData/Roaming, so just back up and enter the "Local" folder.
Once you have this done, open up windows explorer and type in the top bar %appdata%. Change "04" to "01".ħ) Save the edited file and close the hex editor. Change "00" to "01".ģ) Still in the hex editor, go to 0x00BA4B98. Looks like a confusing jumble of numbers? In the top left box of your Hex Editor enter those numbers, and then hit enter.Ģ) In the hex editor, travel to 0x0076DF58.
Then, open your hex editor, and drag the file data.win into the center of it. Go to (C:/ProgramFiles(x86)/Steam/SteamApps/common/Undertale) When you're there, make a backup of steamapi.dll somewhere- I'd recommend somewhere easy to access- then delete it from that folder.
