Action Replay CDX

[spud693]

i need sum help here, i downloaded the gameshark and burned that with dj(with great difficulty) and that works, but the cheats only work on my american import games. i think this is because my dc is a uk pal 1, so i assumed i would need the uk action replay. so i downloaded that as well, but ill be damned if i know what to do with that. it hasnt even got a file extension, so i dont know what i have to open it with! i have been trying all kinds to do something with it, and i managed to open it as a .sit file using stuffit expander, but even then all i have is a .data file and i have no idea what that is meant for. If anyone can tell me what i am meant to do with that action replay file it would be good, because this has really got me pulling my hair out.
thanks
