I've been reading diff'nt threads and have gather bits of info that I can't put together. Ok, 1. the wii has memory or storage space whatever, already added? yes or no 2. if yes, is it for dl'ing VC games, saving wii games, or both? 3. why do i need a SD card 4. what type do I need and where can I get it. 5. what are blocks and how many does it take to save a game 6. I have a Far Cry, and I can't save it when I'm finished, but I can w/ Trauma Center, why is that?
