Hello fellas. I have a 4.1e Wii with Wii flow and a 500GB WD Passport ext HDD. Games are all .wbfs (in a directory titled wbfs), and the HDD is formatted to FAT32. This setup has been working fine with 100+ games installed for over a year. Recently however my son has noticed some games have gone missing like Mario Kart Wii and Lego Batman (all the other Lego games show up). I checked the HDD and they're still loaded on. I re-installed them in any case. I've deleted the Wiiflow cache on the SD card to no avail. I checked the HDD and it found some errors. I reformatted the HDD and re-installed all the games but the same games refuse to be seen on Wiiflow while the others continue to play perfectly. Is it an issue with the Covers (which are on the SD card)? Perhaps I need to delete all the covers and re-install them? Do I need to re-install Wiiflow (it is the latest version)? Any wise words of wisdom on this issue will be very much appreciated. Thanks in advance.
