How do you save a game?

There is a major defect with the auto save, at least in the Wii version, that you may not be aware of. You see, the auto save feature doesn't function properly. The game will save your progress a few times, but you will eventually get an error message when you try to load the game that says: "This file cannot be used because the data is corrupted." It will give you the option of either continuing without saving, or delete the file. Continuing without saving will not fix the problem, as it will make you start over and not save anything! If you choose to delete the file, you will lose your game anyway. Dont worry, nothing is wrong with your console, it's a defect. What I do is that I do a speerdrun through the game and get as far as I can, then I exit all the way to the main menu and then turn the power off. If this is not the case though, go to the pause menu, go to autosave, and see if it is turned on. If that doesn't work, go to the menu when you first turn on the game, go down to autosave, turn it off and then back on. I hope this helps you. The store most likely won't take it back because it's a manufacture defect, not a defect caused by the store.
