Hello I'm new in speedrun of Dark Souls II and I want to test broken% run so for this I need remove the patch and I don't know how to do this .Can you help me ? Thanks for anwser !

Go to http://speedsouls.com/darksouls2:Any%25 and download the Files for Version 1.02, Calibration 1.05. Just replace the files in your \DarkSoulsII folder with these files. Make a backup before you do this and you should be good.

Thanks guys !

You can also run the old patch version from it's own folder and keep the updated version of the game in case you play both.
