Trading Pokémon Yellow-Green GBC, 2024

Trading between Pokémon Yellow and Pokémon Green, unfortunately, isn't possible. While both are Game Boy Color games, Pokémon Green is a Japan-only release, and Pokémon Yellow is the enhanced international version of Pokémon Green. The two games aren't compatible for trading due to regional restrictions.
However, here we have two copies of either Pokémon Yellow and Green ( both Japanese versions) where it is possible, it works also for Pokémon Red, or Pokémon Blue, all of which are compatible with each other.
