Hi Reading about in other forums on wii backups etc i read this: "Getting your backups ready to play After you acquire your backup, check the following: If it's 4 699 979 776 bytes, it's unscrambled. If it's 4 700 012 544 bytes, it's unscrambled with unscrambler 0.4 which adds an extra 32 768 bytes to the file (JESUS release) If it's 4 736 698 368 bytes, it's in raw format and must be unscrambled with this tool." (the link didnt work so i dont know what the tool is) Also is mentioned to patch ntsc iso with regionfrii tool to play on pal units. Is all this actually required as up until this point i thought 'raw dumps' burnt would work? im thinking of using on wiikey if that makes any difference? Thanks for your help!
