To launch this mod, you will need a DeltaPatcher, which you can get from ROMHacking.net or use the one in this mod folder.

1: In "original file" choose the unmodified data.win for Undertale.
2: And for "XDelta Patch" choose the Sanstale x.delta file.
3: Backing up the file is optional, but I suggest you do it anyway.
4: Lastly, go to the cog and turn off checksum validation, otherwise the x.delta will not patch.
5: Patch the mod and enjoy!
