IOS9

IOS9 was used by System Menu 1.0U (other regions used IOS10) and launch/near-launch games. It was also found on Wiis with the Prelaunch System Menu installed. Such consoles were likely for use as game store kiosks. It also comes preburnt on consoles before RVL-CPU-20, although on RVL-CPU-20 and later, it is instead installed by 122E.

| Technical info | |
| Type | Hybrid IOS (Common IOS and System Menu IOS) |
| Status | Active |
IOS9 was the only active IOS that had one content; all other IOSes had a content containing build info, and a content containing the actual ARM binary. When IOS254 was released to overwrite PatchMii, it inherited this unusual property. IOS9 was given a separate content for its build tag in 4.2rev04, and IOS254 was stubbed in 4.3rev02, leaving all IOSes with a separate content for build info.
This IOS only has one LED pattern: blinking.
Titles using this IOS
- System Menu 1.0U
- Wii Sports
- Wii Play
- The Legend of Zelda: Twilight Princess
- WarioWare: Smooth Moves
