'''Roaming items''' are simply map-specific items found in the expanded item pack. Their corresponding memory addresses are set every time the player enters a map. Since many of those data correspond to pointers, the kinds and quantities of those items are seemingly random, may vary between even similar versions (e.g. English Red and English Blue), and cover a wide range of both normal and glitch items.

The "roaming item area" begins with the quantity of item 37, wCurMapTileset, and it technically extends all the way to the quantity of item 128. However, some memory addresses in this area are left unset if they are unused for a certain map (like the data for a nonexistent map connection). In particular, none of the maps have enough warps to actually fill the item pack up to item 128, so for a large number of items, both the item ID and the quantity remains at 0. The sprite set is also only reloaded if it changed.

Modification of those memory addresses usually has no long-term effect (or no effect as all). As such, swapping those items with unimportant items in the normal inventory is a powerful way of getting glitch items.
