Hello, my Wii is on 4.3E. I have had this wii for 1 month, hacked it with letterbomb, and never had a problem, playing everyday emulators and nintendont GC games from SD without a problem. Till one day nintendont stopped recognizing the folder with the isos, and the emulators began to have problems recognizing folders and roms. HBC is able to read all the apps and launch them without problems, but the ones that need to write on the SD, cant (like homebrew browser, or the config files of nintendont or the emulators they just dont save the info, and they crashes when trying to create savestates). I am using a SDHC sony 8gb, but I tried with a Kingston 2gb normal SD, and had the same issue. I tried formatting both SDs, and no results. I think it must be some software issue, because if the SD reader would be damaged it couldnt be able to read from the SD (and never had a problem launching the apps).
