the d2pro9 v2 works for all wii's and when you are installing it the wii-clip way, then u put 2 jumpers on jp1 and jp2 if u want a region free wii so when u burn games, it doesn't matter if they are usa, japan, or european. But if you don't feel like doing any work, i would just install it with the wii-clip without attaching any jumpers because so far all the games from other countries are on Wii ISOs * Wii Torrents iSO ROMs *.
If i were u i would get the pal wii because when u download the games, they are about half the size for some reason.
Hope this helped!
Also i would reccomend buying ur modchip from gmodz.ca
they are awesome. if you want they also do the work for u!
