Okay, I'm still having the issue of split files not playing on my Wii. Since I was originally using WiiBackupFusion on my Mac, I switched over to my Windows partition to see if Wii Game Manager would properly split the files. They are already set as WBFS as I converted them beforehand on my Mac, but when I right click them and select 'Resplit - 4k', it loads for like one second and then it says it's done. Of course, the files are only like 2MB each and the split didn't go through properly. Any reason for this behavior and how to fix it? Thanks!
