The 3.3rev03 update brought along various IOS updates, along with a Wii Shop Channel update. Almost all versions of IOS had IOS37's fix for the signing bug applied to them, just as System Menu 3.3 fixed it in IOS30 and IOS31. Old System Menu IOS versions not used by any games were also stubbed to save space.
This was the first homebrew-affecting update that did not update the System Menu, which led to some confusion about this being System Menu 3.4 or "System Menu 3.3 (Version 2)." While the real 3.4 was released a few weeks later, this update is still distinct.
All modules updated in this version (ES, FS, IOSP, and SDI) were given $IOSVersion version tags, which probably means the code itself was reorganized with IOS28 and became the only method of updating older IOSes. Modules that were not updated did not receive $IOSVersion tags.
- Stubbed IOS4, IOS10, IOS11, and IOS20
- Fixed signing bug in all IOSes that did not have it fixed (except IOS16)
- IOS36 has been replaced with a copy of IOS35
- WD in modular IOSes has been updated to a version from August 2008, possibly for compatibility in IOS35 and IOS36
- The NAND Boot Program in IOS15 and IOS21 is no longer booted when launching the Internet Channel, probably by accident
- The NAND Boot Program itself is still present, but not referenced.
- Updated Wii Shop Channel
- Added IOS51, with above changes
- Added region checks
Compatibility with Wii homebrew
- Twilight Hack still works.
- Homebrew Channel beta8 can no longer be installed, but an existing installation still works.
- BootMii worked when it was released.
These updates are on every game disc whose update partition includes System Menu 3.4 or later.
3.3rev03 introduced the first four stub IOSes, all of which had identical code. They were all size 245760, and were built by
