No. The SD card is basically for storage. It's basically an item for freeing up space on the Wii by transferring over VC games you don't intend to play too often to the SD card. Say you were running out of memory on the Wii and you were halfway through Ocarina of Time, but didn't intend to play it any time soon. You could put it on an SD card to free up memory space until you decide you want to put it back onto the Wii.
