Ilex Forest Celebi glitch without TM33

My previous Celebi Ilex Forest glitch video (https://www.youtube.com/watch?v=BgCJxChdonc) showed getting Celebi with TM33 arbitrary code execution thanks to the duplicate key items glitch and balls pocket corruption.

That requires specific Pokémon nicknames and for my jump code nickname, specific items in the box. You also need to link with a second Generation II game to get your glitched Pokémon nickname into memory, specifically into the third-fifth letters of the fifth Pokémon's nickname.

With this simpler Celebi Ilex Forest glitch, you no longer need to do anything in the last paragraph.

Unfortunately, you still need to use 8F or ws m to get duplicate key items.

You'll need a GS Ball (unless you do the late game alt method described below), and about an equal amount of Machine Parts and an Secretpotions. As before you'll need to fill the key items pocket at 25 items. You also need 2 extra key items.

So if you have 15 key items, this works: 5 Machine Parts, 1 GS Ball, 4 Secretpotions plus an extra Machine Parts and an extra Secretpotion. You won't be able to take it from the Pokémon at first because the key items pocket will be full.

To get them, you can use my previous 8F code (for use with pigdevil2010's or TheZZAZZGlitch's bootstrapping code to item 3):

The code changes the held item of the first stored Pokémon in the current box to the quantity of item 2.

Needed values:
128 - Machine Part
115 - GS Ball*
67 - Secretpotion

Items starting from item 3:

Lemonade x 195 (C3)
Carbos x 222 (DE)
X Accuracy x 8 (08h)
Water Stone x 62 (3E)
TM42 x 34 (22h)
Lemonade x 216 (D8)
Poké Ball x 34 (22h)
TM50 x 33 (21h)
TM11 x 4 (04h)
TM34 x 157 (9D)
TM18 x 201 (C9)

Since we no longer need a glitched Pokémon nickname, a simpler code should be available that only changes the held item. Later I'll make one but you may find the old code useful to track which Pokémon have changed held items.

Edit. Here is my simplified code :

Poké Ball x250
Thunderstone x211
TM34 x157
TM18 x201

04 | inc b
FA 21 D3 |ld a, D321
EA 9D DA |ld DA9D, a
C9           |ret

Steps:

Have a full key items pocket and the two extra held key items first. Have Poké Ball x64 and preferably a Master Ball in the PC.

1) Have Poké Ball at the top of the balls pocket. Have 5 total items there, with a Poké Ball x5 at the bottom.
2) Put two Machine Parts at the bottom of the key items pocket and swap them. Then put two Secretpotions at the bottom of the key items pocket and swap them. The balls pocket should corrupt.
3) You'll get Poké Ball x255. Toss 39 (will become 216, TM25, hex:D8) then switch the Poké Ball x216 to the first position of the balls pocket.
4) Take another key item then repeat step 2.
5) You will get TM26 in first position of the balls pocket. Now do step 2 a third time (remember to take the last key item held) to get 216 ball stacks.
6) Scroll down until you reach your Poké Ball x64, (PC items follow the last valid ball slot).
7) Press select, keep the item 'selected' then scroll to the bottom, where the arrow will no longer blink. It's important to use select because the description of the "?" item is unstable, causing things that include the game locking up and resets. Select will make the text box say "Where should this be moved to?" instead of the item's description.
8) Press select again, and 64 (hex:40) will be written to DA89, causing Kurt to accept your GS Ball in his house in Azalea Town (you'll have to step out and back in his house if you were already there). But bytes for other event flags will be shifted up and the game will think you have no Pokégear!
9) Go to New Bark Town and talk to Mom to get your Pokégear back. Change the date to another day so Kurt 'has enough time' to inspect the GS Ball.
10) Go back to Azalea Town and Kurt will talk about the GS Ball shaking when he was checking it.
11) Go outside then go into Ilex Forest from the west with a Pokémon that knows Cut. Put the GS Ball in the shrine to catch Celebi.

Late game alternative method:

This method requires you to have got coins from a gambler at Celadon Game Corner and met Copycat and found out about the Lost Item (to do this you need to restore power to Kanto). This sets bit 7 and bit 8 of DA8B.

Instead of tossing 39 of the Poké Ball x255, toss 38 and do the rest of the trick (again, go to the absolute bottom of the balls pocket). The value in DA8B will be shifted up into DA89. When bit 7 and 8 are checked in DA89, Kurt thinks you've given him the GS Ball even if you didn't have one and starts to talk about it shaking.
