From Bulbapedia, the community-driven Pokémon encyclopedia.
Each item has a number used to identify it in any game. The following list enumerates them according to the way they are stored in the Generation IV Nintendo DS games Pokémon Diamond, Pearl, Platinum, HeartGold, and SoulSilver.
- There are some items which are not available during normal gameplay, such as region-exclusive items or items which have no actual purpose in the final releases. The only way to get these items, other than the Seal Bag, is through cheating.
- All items from Generation IV appear in Generation V, except for Mail, HM07, and HM08. Most of the Key Items are unobtainable.
- While the blank items in the middle of the list can be displayed, the "items" after the last item in the list cannot. The list can be viewed in-game if such item exists in the save file, but these items are unnamed and the game crashes when selected. If these items are given to Pokémon and put on the GTS, then they will crash the game if that Pokémon is selected.
