"Pokemon Fire Red" is a remake of the original Pokemon game, "Pokemon Red." "Pokemon Fire Red" has improved graphics as compared to the original game, although the characters are the same and the game is set in the Kanto region from the original game. "Pokemon Fire Red" allows players to choose either a male or female character at the game start. While the "Pokemon Fire Red" game does not allow character changes after the initial choice, Action Replay and Game Shark devices can be used to bypass this by entering codes that allow in-game character changes.

Turn the Game Boy Advance power switch to the "On" position and allow the Pokemon Fire Red game a few moments to load.
