IOS 254 is commonly used for various purposes:
- PatchMii uses this as a temporary IOS
- System Menu 3.4 included a copy of IOS9 as IOS254 to block PatchMii (and maybe to break some pirate tools), but Nintendo replaced the wrong IOS number, since most pirate tools use IOS249.
- BootMii as an IOS is installed to this slot.
