Instructions: Press Select to respawn every hidden item, permanently. Works on B2 & W2, any language.
Notice how the Itemfinder isn't picking up the item. I activated the code (which re-enabled the item) and interacted with the tile before the Itemfinder had a chance to respond. If you use the code and wait a second or two, the Itemfinder will "find" it again.
I know for certain that this code only un-flags Hidden Item flags [2820-3032] (to make them able to be picked up again). Every byte modified is either hidden item flag data or unused.
