Ever since 1996, when Pokemon Red and Pokemon Blue were released people have been training and charishing their pokemon. In 1999, they had the option to bring them on yet another adventue in Pokemon Gold and Silver. In 2002, Pokemon Ruby and Sapphire released. This game restricted transferring of Pokemon from previous generations to the new games. Luckily, every release after allowed fans to transfer their Pokemon up to the newest versions.
Sadly, due to the reasons mentioned above, this still means Pokemon from 1999 are still trapped and are begging to see the light of the Galar region. Thats where this comes in. This is the first step into an unofficial protocol codenamed R.I.F.T.S to bring Pokemon from Gold, Silver, & Crystal into Ruby, Sapphire, Emerald, Fire Red, & Leaf Green.
