Can anyone tell me how to save to the internal memory on the Wii game? My daughter is playing My Sims. when we quit the game it has a button to save or quit... but the save button is grayed out/not accessible. I don't have a SD card... do you have to have a SD card to save. I went into the Wii menu and found the data management. I have all these gray boxes which I guess are memory cubes... only 3 cubes are in use. One of them has a My Sims icon... but when I click on in, it ask me to copy, erase or go back. when I click copy it says "no SD card is in use". need help please. Thank you.
