Hi. It seems like it has been ages since i have been on my old Wii. My kids still where, but it stopped when i bought the Wii U. But it seems my kids has been hassling with the Wii. Somehow he replaced channels from the Wii to the SD card... Yet, i cleared space, but it seems i lost blocks... I just can't add the amount of channels and games i used to have... It seems somehow something is wrong... Like hidden maps on PC. Something is using space, but i cannot see what it is.... Way back i made a backup with Bootmii.... Would this help? Or is there any way to upgrade my wii, put the latest ios and so on? another strange this is following... I can boot CDR's but some original games like zelda do not work....... Any suggestion of what i can or should/shouldn't do?
