(adsbygoogle = window.adsbygoogle || []).push({}); I've seen others say that the Yakuza 3 codes are the same between PS3 and PS4, but at least in my save, version 1.04, some item offsets seem, to have changed. If the old PS3 codes work for you, great. Some basic things like difficulty look to have the same offsets and values but I didn't mess with them. But once I started messing with inventory I wound up with a lot of blank and temporary items.

Again, if the PS3 codes work for you just fine, including the item codes, then don't use these. If like me they're not working though, try the below. Items are in your item box at the telephone booth save points. A bit rough but I've sent enough time on it.

Golden Gun:

War God Talisman:

20006904 00010000

Dragon Flak Vest:
20006AE0 000003A8
20006AE4 00010000

Dragon Mail:
20006AB8 000003A3

Although really, you only need either the first or second to completely cheese the game.
