help How do I remove secret base decoations from my inventory?

[JSolves]

After pressing the "Give All Decorations" button in PKHeX I've realized that I now have 25 of each item. Having that many of each item doesn't bother me all that much, but I definitely don't want 25 regional and national dex posters (even though no one can see them it's still somewhat.... unsettling to have 25 of these in my inventory, lol). Is there a way to remove them?

open your save file in a hex editor, go to offset 0x23A00, then change the quantity.

the item quantity is at 0x23A00 + i * 4, where 'i' is the item you want to change (refer to pastebin)

In theory, that is how it can be modified.
