I am retired and have just purchased my very first Wii. In fact, I have never played a Wii game before. I noticed in the documentation that a 32 GB SD card or USB port could be used to save data. I ASSUMED that I would be able to save my game to a USB stick drive or a 32 GB SD card and keep the original CD tucked away to prevent damages. I must say, I was shocked to find out you have to use the CD every time you want to use Fit Plus. There appears to be loaders out there that can be use to put the games on a USB drive but I have also read that attempting to mess with the WII box software can turn your Wii game into a door stop. 1. How do I know which software version my Wii is running at? (When I got the Will box, I followed the instructions and connected to the internet and updated my system) 2. What loader will work with my system 3) How can I prevent or recover if the loader does not work 4) The only games I am interested in running are" Wii Fit, Wii Resort & Will Sports. And only on my machine 5) What is the life expectancy of a CD if you insert/eject the CD twice a day 6) Can you purchase a replacement CD for Wii Fit, Wii Resource, Wii Fit for a reasonable price? Say under $20? Any help would be greatly appreciated.
