Hi all!

Does anyone happen to know a good/reliable site for Game Genie codes for the Sega Megadrive (PAL)?

I've tried the official Game Genie web-site but they only list codes for the Genesis and they don't work with PAL Megadrive games as i just found out with Revenge Of Shinobi and Alien 3.
I've also tried web searches but they just turn up a bunch of useless crap as usual.

Thanks in advance.
