Generation II
- Main article: List of battle glitches in Generation II → Moon Ball oversight
- In Pokémon Gold, Silver , and Crystal , the Moon Ball always has a 1× catch rate .
- The Moon Ball was intended to be more effective on Pokémon that evolve by using the Moon Stone . However, in this generation only, due to an oversight , the Moon Ball has a 4× catch rate modifier if the wild Pokémon has at least two branched Evolutions :
- The first branch must be an Evolution by using any Evolution stone or any other item directly from the Bag . The second branch must specifically use the 10th method of Evolution (index number 0x0A), which does not actually exist in-game because there are only 5 index numbers for methods of Evolution in this generation.
- This occurs because, instead of checking what exactly is the item used to evolve the wild Pokémon, the game checks the memory address that would store the method of the 2nd branched Evolution (if any) of this Pokémon. Additionally, instead of looking for the Moon Stone index number (0x08 in Generation II ), it looks for the Burn Heal index number (0x0A, which used to be the index number of the Moon Stone in Generation I ).
Generation IV
- In Pokémon HeartGold and SoulSilver , if the wild Pokémon is part of an evolutionary line that includes a Pokémon who evolves by using a Moon Stone , it has a 4× catch rate modifier; otherwise, it has a 1× modifier.
