ShowMiiWads is a ‘Wad File Manager’ for Windows. It displays information about wad files, edits them and give a preview of the Banner and Icon. New in this Version is the included NAND Backup Browser ‘ShowMiiNand’ which displays all titles installed in your NAND Backup (No BootMii Backups!).

Changes:

Fixed a bug where every entry was added multiple times in ShowMiiNand
Fixed VC / WiiWare detection (Thanks to giantpune for the hint!)
Added auto updatecheck at startup
