Undertale - Disabling Dogcheck (The Annoying Dog Error Room)

TURN ON ANNOTATIONS A tutorial on how to disable Dogcheck A.K.A. The Annoying Dog Error Room. This enables you to access any room in Undertale without the game stopping you from doing so, but it also means you&putting yourself at risk of horribly corrupting your game due to misuse of save file editing. You&need a hex editing program like HxD. Quote from /u/Nox13last: "Dogcheck turns up if Undertale doesn&want you to see a certain thing, or if it thinks your save files can be damaged by trying to load them. You are at your own fault if your Undertale crashes because you were messing around the gubbins, or your PC spontaneously bluescreens and you lose any open unsaved documents. This information has been checked and rechecked and is correct, and any malfunction in Undertale or the underlying operating system is due to negligence of the user." FOR MOBILE USERS: (CHECK YOUR UNDERTALE VERSION BEFORE DOING THIS) Open data.win with HxD Version 1.00: Use Ctrl + G to go to 007213E4 Version 1.001: Use Ctrl + G to go to 007216D4 Input the numbers 00 01 00 B7 Save. ⠀
