- You can now download an IOS with -ios # in NUSD
- Downloaded IOS wads are now named like so: IOS##-64-####.wad
- Under certain conditions, when downloading a wad with NUS, it will not be saved in a folder, just as the WAD (see ReadMe)
- If missing dll's are detected (WadInstaller or libWiiSharp), Sharpii will ask to download them, if they are required.
- You can now use a .dol file instead of a .wad with the '-dol' in the WAD editor/packer
- Probably a few other little things I have forgotten
- Even more code cleanup and bug fixes
