Now, at this point the game won't work, you need to do either of the two things: disable EAC by renaming/moving EAC files from the game directory, or disabling EAC check. You want to put the two folders from the patcher archive into this folder, and merge the bin file. You can also find this folder by going to steam library, properties of the game and viewing local files. Once you have downloaded the patcher, you need to unpack it in your game directory, over at the steam library or steam directory of your choice, steamapps\common\DB Xenoverse 2.
Here is the link to mega for patcher version 3.3, although you need to make sure it hasn't been updated and that the link here isn't outdated. The patcher is always available from the animegamemods website from this thread: , although to access the download link from there, you need an account. The DLL file it provides makes the game load loose files from the data folder in your game directory over the actual game files in the CPK archives. In order for the game to launch with extra files, you need the patcher made by Eternity.
