Technical info
TypeSystem Menu IOS

This IOS was used by System Menu 3.0, 3.1, 3.2 and 3.3. It added USB Keyboard support.

IOS30 was the first IOS (along with IOS31) to be updated through NUS, as until this point, Nintendo created a new IOS every time they needed to add a feature to the System Menu IOS. This was also the first modular System Menu IOS, as it has a slot above IOS28.

Together with IOS16, IOS31, and IOS37, IOS30 did not have its ES_Identify and /dev/flash access fixed with 3.3rev03. With the exception of IOS16, which got stubbed in 4.0, all of these were fixed in 3.4.
