In Pokémon Gold, Silver and Crystal, the Love Ball boosts the chance of catching the wild Pokémon if they have the same species AND the same gender as yours, instead of the opposite gender
Also in GSC, the Moon Ball doesn't work at all because it checks to see if the Pokémon evolves by using a Burn Heal instead of a Moon stone. This is because the games use
the Moon Stone ID from Pokémon Red instead of GSC
