Is there any Gameshark or Ar Max code to forget hm move without move deleter in Pokemon Ruby?

There isn't a specific GameShark or AR Max code designed solely to forget HM moves without using a move deleter in Pokémon Ruby. However, some codes allow you to manipulate your Pokémon's moves or even change them entirely. One common method is to use a code to replace the HM move with a different move, effectively removing it from your Pokémon's moveset. Always be cautious when using cheat codes, as they can sometimes cause glitches or corrupt your game save.
