Nickname your boxes the following:

Box 1: Ap09é8't5
Box 2: p0'v'v8é7't
Box 3: p555'v7'v'd
Box 4: é(male)2péD9'l
Box 5: 'léZ(multiply x)5555
Box 6: 555A'l(normal x)'d5

You will need 2 specific pokemon in your party. A Quagsire holding TM02 with its first move slot being Return. And finally any level 2-5 pokemon to act as a slide for the code (this might take a few tries)

with the slide Pokémon in slot 3 and the special Quagsire in slot 4, step outside of Cherrygrove City's Poké Mart and make four steps right, listen to bellsprout or machops cry using the pokedex. Go to your bag and switch pockets at least once, use the Coin Case.

This code should give you infinite TM25, in your ball pocket, Save and reset to fix the broken sprites.

Next enter the following box names and use TM25.

Unlike Coin Case glitch you don't have to move in a special way for this to work, and there are no bad side effects (other than corrupted box names which is needed). Misuse however, may cause tiles to shift and move location. (To avoid this, save and reset each time before you alter any codes)

You must move the slide Pokémon to slot 2 and the Quagsire to slot 3 for this to work:

Make sure to replace ?  In box 7 With a symbol provided in the chart for your desired pokemon

Box 1:  Ap'v8é'm25
Box 2:  p0(male)55555
Box 3:  'vAé52p0'm
Box 4:  éJ9p0(female)55
Box 5:  éK9p0255
Box 6:  éL9p'd555
Box 7:  p0?yyéA'd
Box 8:  p0éé(female)'dyy
Box 9:  p0ké0'dp'd



This code above only spawns pokemon from #127 to #251. To access pokemon #1 to #128, use the code below in box 7:

Box 7: p0?'v(space)éA'd


To make the regular encounter table appear shiny, replace Box 7 with:

Box 7: y


Each time you execute this glitch, the slide Pokémon must be in slot 2 and the Quagsire to slot 3 (Don’t change any of their moves or items). Using TM 25 will be the trigger.
