I went back to play this game again on PC, finished the game on PS4 in 2017
I made the warehouse inventory cheat more user friendly to use, but not all stuff available especially Weapon and Armor, they have more complex bytes, so only Potions, Materials, Ores, Charms, Talisman for now.
it will show first 3 slots of the warehouse, it's more convenient to use, easier to swap items you wanted.
the game maybe old, not sure if ppl still need this nowadays lul
Note: this will always show the "actual" very first 3 items you placed in your warehouse inventory, if you have many stuff in your warehouse and the item listing results shown in Cheat Engine don't match what you see in your warehouse, then swap the items in and out of your warehouse, change the item order until you see at least an existing warehouse item thats shown in CE, use that to swap the item you want and then send to your character inventory.
In short: just swap any item that's shown in Cheat Engine to the item you want, and set the quantity, then check your warehouse look for the item by switching the category tabs, it should be shown under the right category tab
Don't try to swap weapon and armor with cheat engine, you will lost your gear, only swap items other than weapon and armor.
