Get glitch items using left-facing shore tile glitch (Red/Blue)
Using the glitch Pokémon 94 (0xF1), it is possible to mutate the fourth item's identifier by +16 (e.g. Good Rod (hex:4D) into 8F (hex:5D)). This will only occur if the original identifier, when converted into binary, did not have bit 0x4 set (Good Rod counts).
- Any old man glitch name character (name position slot 3, 5, 7 or 9) corresponding with a Trainer. See The Big HEX List.
- A very strong Pokémon, preferably a Level 100 one with several X Speeds and at least one X Accuracy to secure a one-hit KO on six Level 250 Pokémon with Horn Drill, Fissure or Guillotine. Tauros is a good choice.
1. Battle the Rocket on Silph Co. 11F
3. Battle any glitch Trainer from the left-facing shore tile, until they send out a "94". Afterwards, your fourth item may have changed.
