Sapphire Version. This is an in-depth walkthrough for Pokémon Ruby and Sapphire for the Game Boy Advance. These pages detail the original iteration, not Omega Ruby and Alpha Sapphire. The guide for those can be found here.

Regardless of how many hours a game takes to complete via a direct line from the beginning to the end, there are variables present. Especially since this series always puts a focus on catching all of the pokémon, which can take well over 100 hours for the truest, most dedicated Pokémon trainers.

Capturing Rayquaza is one of the final things to do in Ruby and Sapphire, and it requires the player to have beaten the Elite Four in their entirety. Because it requires completion of the Elite Four to show up, many players missed their opportunity to catch this amazing beast.
