Pokémon Blue: 151 Version

Blue 151 Title"You've finally been granted your Pokémon trainer's license. Now, it's time to head out to become the world's greatest Pokémon trainer. It's going to take all you've got to collect 150 Pokémon in this enormous world. Catch and train monsters like the shockingly-cute Pikachu. Face off against Blastoise's torrential water canons. Stand strong when facing Pidgeot's stormy Gust. Trade with friends and watch your Pokémon evolve. Important - no single Pokémon can win it all. Can you develop the ultimate Pokémon strategy to defeat the eight GYM Leaders and become the greatest Pokémon Master of all time?" - Game Freak


Fuchsia CityIn this special "151 Version," You'll be able to complete your Pokédex without the need to connect with other games via the game-link cable (though you totally still can)! Most of the game is left as "vanilla" as possible to remain as faithful to the original release as you remember it, though some text has been modified to no longer reference "real world" locations. However, this edition does not change difficulty, sprite-work, music, evolution methods, trainer parties, running speed, rebalance moves, modify typing or introduce anything new which might "modernize" or "fix problems" with the original release!

How to Use the Patch

The ROM-hack file in the download section cannot be played by itself! It must be applied to an original, legit copy of this exact .gba rom: Pokemon - Blue Version (USA, Europe) (SGB Enhanced) - I cannot tell you where or how to find that exact titled rom (it cannot be a "Rev 1," and cannot be in any other language, etc.), but if you have a rom like this, check it using this link https://www.romhacking.net/hash, and compare the information it gives you to this info, here:
