Kingdom Hearts Dream Drop Distance - Inventory

Every entry is stored as 0s. Whenever the player obtains an item ingame, the item’s specific location is updated with the item id.

Eg: The address where Sora’s Ultima Weapon is will be “00 00”. Whenever you obtain it, it will change to “08 02”.

For items that can stack, 2 additional bytes are used to store the amount of the item the player holds.
