I am still confused about SD cards. I have saved games as per usual on the wii itself and then backed up on the SD card (2gb). I assumed that it would be possible then to carry out an update of the SD card save in order to maintain that the card contained the most up to date progress in games. When I then go into the Wii Data Managment section and tell it (for example) to save Zelda, it tells me that the file already exists.....i.e it will not let you overwrite. To copy the latest version you then have to delete the SD file and copy again.....is this right or am I missing something.
