Celebi turning into Mew in the Time Capsule notes

Remember to have no Pokémon in the party with Generation II moves.

Using this set up of Crystal_'s Coin Case as a memory editor method https://www.youtube.com/watch?v=Y9r9Gy3Shi8
(possibly this set up too, I have not confirmed) https://www.youtube.com/watch?v=ffZjCabeNr4

..You can use the Coin Case with certain box 9 nicknames to write the following code at $FB0E+:

FB0E+
26 FF 2E 86 3E 18 22 3E 71 22 2E F9 3E 3D 22 3E 20 22 3E FD 22 3E C3 22 3E 2D 22 3E DB 22 C9 3E FB EA 3A 80 C9

-We also use write 06 to D67E (Pokédex mode) to get glitch Pokédex mode 06. Valid Pokémon modes include old Pokédex, new Pokédex and A-Z mode.
Viewing glitch Pokédex mode 06 serves as an access point for executing the code at $FB0E.

-We also write FF to DA23 to get a ????? (FF) for Johto guard glitch.


This is @FB0E:

ld h, FF
ld l, 86
ld a,18
ldi (hl),a
ld a,71
ldi (hl),a
ld l,F9
ld a,3D
ldi (hl),a
ld a,20
ldi (hl),a
ld a,FD
ldi (hl),a
ld a,C3
ldi (hl),a
ld a,2D
ldi (hl),a
ld a,DB
ldi (hl),a
ret
ld a,FB
ld (803A),a

What it does:

1) Writes dec a (3D) jr nz,FFF9 (20 FD), jp DB2D (C3 2D DB) to FFF9+ (an address that executes by itself).

When the processor gets to FFF9, it:
- Jumps only until the register 'a' is 0. Apparently gives the processor enough time for DMA to complete, for the trick to work on a real console.
- Jumps to DB2D to activate code.


2) Writes ld a,FB; ld (803A),a to DB2D.

ld a, FB; ld (803A), a - makes the game write FB to 803A until the game is powered off, allowing Celebi to convert into Mew.


Thanks luckytyphlosion for his RNG plays Pokémon trick for Red and Blue; the basis of this. I altered the jump address at FFFC and used it on Pokémon Gold.
