I have wBFS Manager 3.0 loaded on my PC running Windows 7 Home Estentials. I am trying to load some Wii ISO game files onto a 16G Cruzer (SanDisk) 2.0 Flash Drive which I have formatted with WBFS Manager. All the files Im working with are approximately 4.7G. Some will load on easily and plays correctly but others will not load on. The one that does load shows as a smaller size. IE: "New Super Mario Bros." is showing as 4.37 in Windows Explorer but is showing as Estimated size .35GB, ISO size 4.37GB in WBFS Manager and it plays fine on my modded Wii console but "Call of Duty, Modern Warfare" also 4.37GB in Explorer but shows as 4.08GB, 4.38GB ISO and is too large to install. Whats the difference? Is there some kind of conversion I need to do?
