IMPORTANT ANNOUNCEMENT - March 2023
Warning! Effective in v7.0.0, many of the WADs in ModMii's temp folder from older versions will be deemed invalid going forward and will be automatically re-downloaded (more details in changelog). To correct the files in your temp folder all at once, download the items from the bundled "NUS_2023_Changes" download queue. After ModMii's downloaded files to its temp folder for future use you can delete COPY_TO_SD. (L)oad a prepared download queue to get started. Re-download from NUS while you can as Nintendo servers could shut down at any time!
IMPORTANT ANNOUNCEMENT - FEB 2018
Unfortunately, effective February 2018 ModMii's auto-update feature is broken on any version older than 6.4.5 so you will need to manually download and run the latest installer from HERE in order to start getting updates again.
How to Use ModMii
Note: The files available for Advanced Download can be patched and have their version/slot numbers changed.
User Defined Custom Downloads can get ANY IOS (and optionally patch it), MIOS, or System Menu.
