How to get Pokémon Red and Blue’s pea soup coloring and a Game Boy border on your 3DS

You can finally play the original Pokémon games on your 3DS, but Nintendo’s handheld has a few secret ways for you to maximize your nostalgia.

If you buy Pokémon Red, Blue, or Yellow from the 3DS eShop, you can play them in their original resolution with a virtual Game Boy border. With a few button presses, you can also play Red and Blue in their original pea-soup green color. These are tools built into the 3DS, and they work with every Game Boy game available for the Virtual Console.
