In Pokemon Gold, Silver and Crystal there are a total of six unused item effects that grant the holder immunity to one status:
Effect 0x14: Prevents holder from being poisoned
Effect 0x15: Prevents holder from being burned
Effect 0x16: Prevents holder from being frozen
Effect 0x17: Prevents holder from being put to sleep
Effect 0x18: Prevents holder from being paralyzed
Effect 0x19: Prevents holder from being confused
The routine that takes care of applying these effects is the battle command that handles the respective status. For example, the battle command that handles the effect of sleep moves, first checks the target's item and prevents sleep if said item's effect is 0x17. In addition, a text box is displayed saying [PkmnName]'s protected by [ItemName]. However, this text box is not displayed if the status would be inflicted as a consequence of a secondary effect of a damaging move (this, for example, excludes Poison Stings's poison or Thunder's paralysis as well as every possible case of burn or freeze).
Since there are no items that use these effects, I modified the effect byte of Ultra Ball and Super Ball in the item attribute table to make this video possible.
