So, i'm trying to create an ISO file from a Wii Backup (WarioWare Japanese). I'm using ImgBurn, and when it reads the disk, it shows the Disk Size as: 4,700,307,456 bytes. The "original" ISO was 4,699,979,776 bytes. So, why it shows that size? Do I have to do something else or i can do the Backup? Thanks in advance!
