TheZZAZZGlitch's looping map trick

TheZZAZZGlitch's looping map trick to obtain 8F or ws m allows you to bring up every item into the regular items to keep, except for possibly the non-functionable PP Up copy (32h) and TM55 (FFh, but you can keep the key item HM05 which works the same). You can dig up items of your choice and keep them if you bring them up with Select and then Teleport away.

Steps:

1) Walk to this place.

2) Swap an item with an ID of hex:33 or greater into the Nugget x1 found at item position 35, such as Poké Doll or X Special.
3) Keep walking right (to increase the item ID by 1 each step) or left (to decrease it by 1 each step) to change the item, until you find a HM02: Fly.
4) Press Select to bring it up to the top of the items pack and then Teleport away.
