Any Gameboy Game Genie Codes Online?

[okame]

I have a Gameboy Game Genie and  a Japanese copy of Yoshi's Cookies. Is there a site for Gameboy Game Genie codes, both English and Japanese? I'm thinking of getting some more Japanese Gameboy games (especially the ones that didn't make it here), and the Game Genie would be nice to use as more than a holder for games I don't have cases for. Links, please!
