If this has been asked before, I apologize, my searching didn't come up with anything.
Is it possible to transfer downloaded games, Guitar Hero/Rock Band songs, channels, etc. to a memory card and then to a computer's hard drive for storage, and then back to a memory card and to the Wii?
I ask because I'm interested in downloading some songs for Beatles Rock Band and Guitar Hero 5 and I don't want to have to deal with a handful of memory cards and would like to store extra files on one of my hard drives for safe keeping.
I'm hesitant to try it without knowing for sure that I won't lose anything in the process.
