DOP-Mii originally known as DOP-IOS MOD, is in short; A homebrew Wii system tool that can do almost anything to your Wii.

Changelog:

IOS Menu Changes

* You can now select what version of an IOS you want to install. Including Stubbed IOSes if you want to revirginize your Wii.
o NOTE: Just because the option is available to install any IOS version. Not all Wiis will support the lower IOS versions.
* Uninstall IOS feature
* Added BC & MIOS Support
* Menu now driven by a homegrown title database. It now knows what IOS versions can have what patches applied to them.
* IOSes can now be installed into empty Slots. To perform the install Hold A then press +.

Channels Menu

* Can now be installed via WAD. Menu will tell you the WAD Filename it requires. If the Channel requires 2 different titles it will display both WAD filenames.

System Menu

* You can now upgrade or downgrade to ANY System Menu version.
o NOTE It is not recommended to downgrade below 3.2 if you have a newer Wii. Rule of thumb is if you can't install BootMii as Boot2 then you should not go below 3.2.
* Installer will check to make sure you have the correct IOS with the correct IOS Version installed before installing the selected system menu. If the IOS is not installed, it will prompt and install the IOS.
* If Priiloader is installed, it will temporarily backup Priiloader. It will prompt you at the end of the System Menu installation if you would like to restore Priiloader.
* Can now be installed via WAD. Menu will tell you the WAD Filename it requires. If IOS is required it will also provide the IOS WAD filename.

Boot2 Menu

* Yes there is now Boot2 Upgrade Support. We were requested to add it in. I would like to give a special thanks to Bushing for providing me the ES_ImportBoot code to ensure that Boot2 gets updated properly. If you are already at Boot2v4 you will not get the option to upgrade as you are already at the latest version.
o NOTE: If you have BootMii installed as Boot2. Beyond our control it will wipe it out. You will need to reinstall BootMii as Boot2 after Boot2 has been upgraded.
o NOTE: As a reminder, when your boot2 is upgraded, it CANNOT be downgraded.

Other Changes
