Hi. Felix here.

Please, BACKUP YOUR SAVES before doing anything. I cannot emphasis this enough.
I am not to be held responsible for any loss of data.


[STEAM CLOUD]

For this mod to work you may need to turn off Steam Cloud save files backup:
-> right click on Yakuza 0 in your Steam Library
-> Properties
-> General
-> turn off Steam Cloud backups


[INSTALLATION]

From this moment forward the process is quite simple - just paste the save files to:

<your Steam installation folder>/userdata/<your Steam user ID>/638970/remote

And paste the remotecache.vdf to:

<your Steam installation folder>/userdata/<your Steam user ID>/638970/

Now, if you were to launch the game, you may encounter the correct amount of save files, but most of them will display as "Unknown" - this is caused by your game not having enough save files made. If a save file was never made in the first place, the game cannot possibly load it. You most likely do not have as many saves as I do, so you may need to rename the files, for example:

SaveData0053 -> SaveData0000

This should replace your Save 1 with my Save 54. Note the shift in nummeration.


[DIFFICULTY]
All saves are on EASY mode, this is because I needed to get through the story as quick as possible. You can always change the difficulty in the pause menu settings, though.
