=== Get a ×255 item stack ===

[[File:Oldman1.png|thumb|Step 2: Just in case you don't remember, this NPC is [[Old man glitch|''the'' old man]].]]

The goal of this step is to get a stack of any item ×255 in the bag. Since the normal limit for an item stack is ×99, this goal will require a glitch. Namely, we will duplicate the 6th item in the bag by encountering either [[MissingNo.]] or [['M (00)]] through the [[old man glitch]].

 

# '''Go to Viridian City, and talk to the old man who shows you how to catch Pokémon. Watch his catch demonstration''' (by saying "No" when he asks if you are in a hurry).

# '''Immediately Fly to Fuchsia City<ref group="note">The more well-known location to perform the old man glitch is the eastern coast of Cinnabar Island, but it actually works with any "eastern shore tiles" that can be reached from a Fly destination without going through an area with grass encounters. This guide will use the shore tiles on the east side of the Seafoam Islands because they are closer to a location that can help us get 8F easily later.</ref>''' (without otherwise leaving Viridian City).

#* For safety, save the game now, since there is a possibility we may need to reset later.

# '''Surf along the shore for wild encounters. We are looking for the glitch Pokémon [[MissingNo.]] or [['M (00)]]<ref group="note">As mentioned on the [[old man glitch]] page, the possible encounters depend on the player's name, but at least one of the glitch Pokémon we are looking for should always be available.</ref>, which looks like one of these:'''<br />[[File:MissingNo._RB_SGB.png]][[File:Kabutops_fossil.png]][[File:Aerodactyl_fossil.png]][[File:Pokémon_Tower_ghost.png]]

 

=== Perform dry underflow ===

Now that you have a ×255 item stack, you can save the game and experiment with it if you want to.

 

=== Obtain 8F ===

Once you have access to the [[expanded item pack]], obtaining 8F, or indeed any item in the game, is quite easy. The reason is that the contents of the expanded item pack actually correspond to unrelated game data — such as your coordinate on the map — so they can be easily manipulated. On the other hand, that also means that messing with the contents of the expanded item pack may affect the game state, and can even be dangerous. Follow the below steps in order to obtain 8F safely.

# '''Swap this item with a useless item in your main inventory.''' (The ×0 stack at the top of your inventory you've just created in the previous section should work fine: You should have at least two ×255 stacks of the same item below, which can duplicate themselves if you somehow need more.)

# '''Immediately Fly away.<ref group="note">By swapping the 35th item, you have corrupted your X coordinate, so trying to move around on the map may have unexpected and confusing effects. Depending on which item you swapped it may be possible to leave the map by Surfing and/or walking, but the safest option is to just Fly away. There is a technique named the [[Celadon looping map trick]] which makes use of such a X coordinate corruption to obtain items with too large an internal ID to be obtained on Route 20, but you won't really have a need for that since once you set up ACE you can obtain any item more easily.</ref>'''
