Still in version 1.0, no changes were made, I just updated the description text shown when running the PowerShell scripts to include a Wii mention, clarifying this way that the scripts will work for Wii ISO files too.
Note: change $compressionLevel value to 8 (instead of 9) in the script file for Wii ISO files if the script (better said, if DolphinTool.exe) throws any conversion error.
A standalone DolphinTool.exe v5.0-21264 (x64) is included in this package.
