This only works with the PAL version of the game! How to load the save:

CONSOLE (Wii/WiiU):

Copy the "private" folder onto an SD card. When inserting the SD card into your Wii or WiiU, move the TfS Wii block to the system (you first have to erase the system's TfS Wii block in the save file manager). Booting up the game as normal should show you the profiles with the save you just downloaded.

EMULATOR (Dolphin):

In the emulator menu select "Tools > Import Wii Save" and select the "data.bin" file from "\private\wii\title\SPXP"
