How do you enable Debug Mode
I tried every video on youtube but I just don't know how to get it working. I have Hex editor and opened data.win with it I type in 00725D8C but I dont know which value to change they said to change the value to 01 but which row do I change the value on. plus im using the latest version which is 1.001 I think.

what do you mean? it doesn't work anymore?
When you open the editor you have to press CTRL and F at the same time. Type in 725B24 for 1.0 or 725D8C for 1.001 in the seach bar. When you press enter you will automatically be at the value you need to be. Just type in 01, press enter, and when it asks you if you want to save changes press yes. This should activate debug mode. I've used this mode a few times myself and it worked every time.

Which row do I have to change the value on though? I have the game on Steam which is updated to the latest version 1.001 and I typed in 725D8C and it gives me all these kinds of value on differents row for exampe row 1 would have 10 row 2 would have 00 row three would be 01 ect... with many diffrent values. Also on youtube they said I needed to delete Steam_appi.dll DO i need to do that too? or I dont need to? another thing does it work on Genocide I started the Genocide story.

You can test if it's on or not by using one of the keyboard short cuts. For example, If you're in the game and you hold backspace and begin walk faster, then you know debug is on :>

for people who have difficulty enabling debug mode:

Go to steam undertale settings by clicking properties
go to Betas section
under the "Select the beta you would like to opt into", click the old_version_101
now update the undertale
click the gear icon from the undertale library page
click Manage > browse local files
now go to bottom of the folder
and delete steam_api.dll file
open a HxD editor ( I use this one and it is safe to download: https://mh-nexus.de/en/downloads.php?product=HxD )
click data.win file from the folder that just opened by steam
drag this data.win file to the HxD editor you just opened
now press Ctrl G to open the search (in the HxD editor)
type 725D8C and press enter, the cursor will go to that location
At that location you will see its value is 00
change it to 01 (if a window pops up saying "it will change the file size, are you sure?" do NOT click ok, it means you changed wrongly, click cancel)
and save the file by pressing Ctrl S
You can now close the HxD editor and open the undertale from steam and you will see that the debug has enabled
Have fun!



To download the HxD editor:

Go to the link I provided above
click any translated version for your choice to download
now double click the downloaded zip file
open the zip file or extract it
you will see it has a file called setup.exe
double click on it
modify the installation settings.. whether you want a desktop shortcut or not etc.
click continue, ok etc...
and it will install it to your machine
