Alternative Select glitch walk through walls glitch (Pokémon R/G/B Japanese)
Read description for more information:
Requested by kimagurena-san who was looking for help in getting this glitch to work.
This is a select button glitch that lets you walk through walls. It's similar to the Safari Zone no-clipping glitch (if you land the 500th Safari Zone step on a ledge you can walk through walls), but is quicker. You need at least 13 items.
A side-effect of this glitch is that it gives you more than 20 items, which allows for many more exploits.
Steps:
1)Highlight the 13th item with Select.
2)Exit with B,B, enter battle and select the third Pokémon from the ポケモン menu to swap it with a glitch Pokémon.
3)Run from battle. Open the items pack menu. You should have over 20 items.
4)Highlight the 32nd item with Select and exit the menu with B,B enter battle and select the third Pokémon from the ポケモン menu to swap it with a glitch Pokémon again.
5) Exit the battle and the bicycle theme should play.
6) Jump off a ledge and you'll stay in mid-air and will be able to walk through walls.
The walk through walls effect will stay when you Fly or Teleport away, but disappears after entering a building.
Notes:
If you move the cursor to the 32nd position via your items storage box, you can highlight it with select and replace the third Pokémon to get the Bicycle music to play. The walk through walls effect doesn't seem to work this way, however.
