Hello,
So apparently I got too much time on my hands 😉 so i went ahead and mapped out all the items in these 2 remastered games. I found it pretty helpful on my own play-throughs and figured i might as well share it in case someone else would find it helpful.

Note for Yakuza 6 & 7: The save format for this game is in text rather than the usual binary. To edit items in this game find the "carry_item" array and add to it for the item's you wish to add.
For Yakuza 7 the Item Box array in the save is called: "box_Item" and works the same way as inventory, however it does not contain any equipment as those are stored separately.
Few Notes:
In Yakuza 7: Like A Dragon items. Note: No equipment as they are handled in a different way in this game than what we're used to. However, you can just craft them if you give yourself the required materials.
User question - For Yakuza 7 How to edit the item amount from one digit to two or three digits? I can only change it up to 9, no idea how to add more than that
You will need to export the save and edit it in an editor because Save Wizard imports it as binary, it is clear text however so after you export it you can just open the save in a text editor, find and change/add your changes and save it, then re-import it into save wizard. You cannot make the changes directly in save wizard if it changes the size of the save because it is in binary mode.
