Item description:

This is a fairly simple ROM hack that adds the female trainer, Green/Leaf from Pokémon Fire Red and Leaf Green into the original Pokémon Red and Blue, made using pret’s pokered disassembly. Much like in Fire Red and Leaf Green, Professor Oak will ask the player if they are a boy or a girl when the game begins, and the game will continue as normal from there, including altering all references to the player’s gender depending on their decision.
