I'm doing walkthrough on various games in my Livestream channel.
All of my walkthroughs are recorded on this channel: http://www.livestream.com/liquidcrystal/
Pokémon Liquid Crystal
Pokémon Liquid Crystal is a hacked version of Pokémon FireRed, been modified to create a remake of Pokémon Crystal, with tons of new features added by the creator, such as Giovanni's appearance, and even traveling to the Orange Islands!
If you want to play this game yourself, click below to download the game and the required emulator.
If you haven't played a hack before, here's a quick guide on how to patch it.
Here's my Liquid Crystal blog.
Pokémon Ruby Version
Pokémon Ruby Version is not a hack, it's an original game where you travel around the world of Hoenn.
Here's my Ruby Version blog.
