Steps:
0 Make sure you have at least 1 of the item you want already
1 Pick a character slot
2 Pick 1 or 2 of the codes
3 Apply them
4 Make sure your PS4/5 isn't connected to the network
5 Go back into the game and craft, sell, or stash to your hearts content
6 Make sure you don't have 9999 of any items shoot for 99 or 999 on your person
5 Resume online play
6 If you can make these into better/item grouped/combined codes by all means go ahead... I'm sure we all would appreciate it IE: All Grave Gloveworts @ 9999 in one code or All crafting items @ 9999 or All upgrade stones of one type @ 9999... ect.

I know for sure that these codes will work on Slot 2... I tried a bunch of the other ones I whipped up but these were the only ones to pan out.
There is a pretty good chance you can only use 5 at once, so I will have to keep testing.
EDIT: After further testing the fastest way to get max items with the codes I put together seems to be doing them 1 at a time
which is pretty slow... and Save Wizard no longer appreciates me for testing my codes in this manner... but in my defense I tried to use all of them at the same time, I tried using only 5 at a time, and each attempt got me different results. So that's the best I can do.
