what I do
Mr. MissingNo. 15:28, 10 May 2023 (UTC)
what I do is:
- arbitrary code execution with glitch item 0x6B in Pokémon Red and Blue, because of its effect pointer at CD35 and that it can be used for this by putting the bytes [C3 22 D3] at CD35, I use GameShark codes (01C335CD, 012236CD, 01D337CD) to do so.
item 0x6B arbitrary code execution (Red/Blue only)
item 0x6B executes CD35 when used, therefore I use it for arbitrary code execution.
the bytes (C3, 22, D3) are required at CD35.
get any Pokémon:
this setup allows me to get the Pokémon that I want.
items for this setup:
- item 0x6B, any quantity
- any item, any quantity
- Repel, x(species)
- X Speed, x14
- Ultra Ball, x64
- TM05 x72
- Lemonade x201
bytes needed at D31D:
07 6B FE 04 AC 1E FF 43 0E 02 40 CD 48 3E C9
ASM instructions:
CD35:
- jp D322
D322:
- ld e,$FF
- ld b,e
- ld c,$02
- ld b,b
- call 3E48
- ret
