I am concerned with how many blocks I have left free on my Wii. I can't remember what I started out with, I think somewhere in the range of 900 and something? I am now at 468 blocks and I am a little worried I will not be able to gain what I have lost. I installed a few VC wads and used WAD Unistaller to remove one. It didn't free up much space. How can I check where most of the memory is being used and the best way to free it up?
