Pokémon Trading Card Game, titled Pokémon Card GB in Japan, is a video game version of the super popular tabletop trading card game based on the Pokémon video game series. Pokémon Trading Card Game released in 1998 (2000 outside Japan) for the Game Boy Color and was received well by both Pokémon fans and industry critics alike. It is no surprise that game received a sequel, entitled Pokémon Card GB2: Great Rocket-Dan Sanjō! (Pokémon Card GB2: Here Comes Team Great Rocket!) – sadly, it was Japanese-exclusive and never saw a western release.
Enter Pokémon Trading Card Game 2: The Invasion of Team GR!, an English fan translation of Pokémon Card GB2. ROM hacker Artemis251 has completed the patch which enables English-speaking fans to finally play the Pokémon Trading Card Game sequel, featuring a new group of baddies called Team Great Rocket, the ability to play as a female character and cards exclusive to Japanese vending machines.
All you need is the original ROM file for Pokémon Card GB2: Great Rocket-Dan Sanjō! and the fan translation patch which you can download here, and you’re good to go.
