Game with Custom Case Cover Art Great Condition. Save File Works. Game Tested and Works Great. Pokemon Liquid Crystal (Game Boy Advance) is a custom made game. This Game Boy Advance game is region free. Pokémon Liquid Crystal is a ROM Hack developed for the GBA system using FireRed as the base. It’s a complete Pokémon Crystal Remake of the the GameBoy Color classic. The story is the same as the Original Crystal with a load of extra events and even a brand new region to explore. The internal clock function is disabled for this cartridge. It will still play as normal and you can finish the game and save as normal without the internal clock function. That is just something that would work on an emulator with the proper settings, but not with the cartridge. Pokémon Liquid Crystal has some unique features such as the ability to travel to the Orange Islands region, a never before seen region in the Pokémon games. That’s not all, we have a bunch of features waiting for you to discover while playing the game such as Berry Growing, Diving, Hidden Areas and a ton more!
