Technical info
TypeCommon IOS
StatusActive


IOS28 is the first IOS to be split into multiple modules, each its own ELF ARM binary, rather than all of IOS being part of a single monolithic binary. Its ES module includes ioctls that retrieve shared contents.

This IOS also uses a different range of memory, so it must clear memory differently. Because IOS22 and below did not do this, IOS28 also clears it if one of those IOSes is reloaded to.[1]

Titles using this IOS

The only game that uses it is Metroid Prime 3: Corruption, and this IOS was included in the update partition of the disc.
