Hi there -- newbie Wii user here trying to get a handle on the system. I just bought a Wii and tried to start Pikachu's Adventure -- I get an error message telling me I need 95 blocks of memory and only 43 are available. Seems odd that a new console doesn't have enough memory to run a game. Only two other games played previously (New Super Mario Bros and Mariokart) -- both had no problems. Do I need to buy extra memory? Insert an SD card? Any guidance very gratefully received!!
