Ok, you are in dubai? Why dont you import from a site which can ship to there, if there is a site. Im not sure. You'll have to wait for someone else to answer that.
Ok i dunno if you fully understand. The wiikey is a modchip which you usually have to install inside your wii via soldering etc. You can import the wiikey i believe some stores can ship to dubai not sure. Then you'll have to either solder it in yourself or get somebody else to do it for you. After that happens the mod chip tricks the wii into thinking the game inserted is of the same region as the wii, thus allowing you to play pal games on your ntsc wii.
PS: Not all pal games will work on your NTSC wii, you'll have to check the Wii Pal compatibility list for that.
