This is mostly for the sake of knowledge, as the USB loaders get around the issue, but: Why do games keep showing "Wii System Update" in the disc channel, when I already have the latest version of the IOS used by that game? For example, Tiger Woods PGA 12 asks me for a system update. Wii Backup Manager tells me that this game uses IOS 56. According to SyscheckGX, my version of IOS 56 is rev5662. Could it be that some games have lower level updates to these IOS's, not evident in the 5662 version number? Thanks.
