Line 3:
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.
 
==Attributes of items beyond the item limit==
Line 30:
Note that this equation does not apply for items 129 (0x81) through to 256 (0x00) because those items represent items 1-128 again.

This is very simple : you need to buy three items to return your menu to normal.

Warning : the first item will be lost !
 
With ACE[[arbitrary code execution]], the following code should work :
<br />
<code>
Lemonade x(# of items in your inventory before the glitch)
<br/>
TM34 x211
<br/>
hex:1C (Earth Badge) x201
</code>
 
= Generation I activation =
 
== Item underflow glitch ==
This method was discovered by MrWint.
Line 44 ⟶ 60:
The player should open their item inventory, and toss their first item until the Item menu stops "responding".
<br/>
Then the player should remove an item from their inventory with an event. Then, opening the Itemitem pack allows the player to edit arbitrary RAMunrelated portions of the memory as if they were items.
 
=== Explanation ===
Line 52 ⟶ 68:
 
=== "Dry" item underflow glitch ===
This glitch was documented by Luckytyphlosionluckytyphlosion ([http://forums.glitchcity.info/index.php?topic=7175.0 thread]).
 
It is a better method because it doesn't require the Saffron guards to be thirsty or a Fossil.
Line 108 ⟶ 124:
</code>
This basically changes the item counter to hex:FF
 
 
== Using Gameshark ==
Using a cheating device is not needed, however, the code 01FF1CD3 (Yellow) or 01FF1DD3 (Red/Blue) will give the player 255 items.
The code 01FF1CD3 should set the expanded item pack correctly ; although with Gameshark, you don't much need this trick because you can edit RAM without this trick.

Notice : when scrolling down the list, the cursor may seem to freeze ; in that case hit A until the cursor responds again. This happens when the game prints a large name which spans multiple lines.
One can access an expanded Poké Balls pocket through [[duplicate key items glitch]] abuse.

Like said earlier, it can be used to speedrun the game, as changing the 36th item allows to change warp locations.

Here is a list of interesting items to mess with :

*In Pokémon Crystal, the glitch description of item hex:00 will usually freeze the game. This can be avoided if the player presses Select on another item to bring up the text "Where should this be moved to?" before scrolling down.
<br/>
*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.
Warning : the first item will be lost !
