For example, in Red, Blue and Yellow the normal maximum number of bag items is 20 and the maximum number of stored PC items is 50 and under normal circumstances, trying to obtain another item will bring up a message that there is no more space.

In actuality, the maximum amount of items that the player can use, swap or toss is 255 or whichever value a 'number of items' address, such as D31D (Red/Blue, D31C (Yellow) (number of items in the overworld items pack) becomes corrupted to.

*In Red, Blue and Yellow, when scrolling down the list, the cursor may seem to freeze ; in that case hit B until the cursor responds again. (If A is used, and is pressed while a long-name item is selected the game will crash and save data may be partially overwritten.) This happens when the game prints a large name which spans multiple lines.

*The expanded items pack is useful for Pokémon 'glitched' speedruns as it allows the manipulation of many addresses such as map destinations, text pointers (for [[text pointer manipulation]]) and so on.
