Pokémon Red and Blue: Difference between revisions

In most cases, glitch items are obtained from the [[expanded item pack]]. Putting the game into certain states will cause certain items to appear in the expanded item pack, which can either be used from there or switched into valid item slots to preserve them, although care must be taken because modifying the expanded item pack also changes the game state. The [[Celadon looping map trick]] can help the player obtain any item, except [[Cancel (Generation I 0xFF glitch item)ItemDex/RGBY:255|Cancel/TM55]], as long as the player knows its internal ID. Alternatively, in both Red and Blue, it is possible to find all glitch items in the game as [[roaming items]], although it is not a trivial task to find out which map has a specific roaming item.
