- 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.
