It constantly says when I try to apply the patch "An error has occurred: xdelta3: target window checksum mismatch: XD3_INVALID_INPUT"
I don't understand what I do wrong, I have Undertale on steam so the "original file" is correct and the only thing I need to do then is to use the xdelta file for applying the Steam to Mobile patch but this is what happens all the time.

Okay... I have copied everything in the Folder but when i click on the .bat file that Console thing opens for 1 Sec and then nothing happens ._.
