For the new games either you can update it but firmware 4.2 on the wii doesnt like modchips so it will block your out of region games. I have newest update from wiikey on my wiikey2 and it doesn't allow you to play the newest game. In the end you are gonna soft mod your wii. Install the lastest ios. Ios is whats needed to play games. So when you install the latest ios you will be able to pop in the game that you downloaded and just play them. Its as easy as that. You can do an upgrade from the game disc itself but I no nothing about that sorts. Also you might wanna configure the wiikey so that it can block updates and other stuff that you want it to do.
