Is there a way to store the Wii game saves direct to the SD or other medium, instead to the WII memory blocks. Running out of blocks, need now to copy them 1 by 1 to SD!

This in order to keep the Wii memory clean and be able to run games without doing house keeping!

I did perform a search but was not able to find the answer!

Thanks for the guidance of a new born in Wii world
