This also appears to be the first IOS to support [[:/sys/disc.sys]]; this probably means Metroid Prime 3: Corruption requires special privileges.

IOS28 seems to have been modularized completely separately from [[IOS30]] and [[IOS31]]; because those were the IOSes that all other modular IOSes were branched from, IOS28 has a unique set of modules. IOS28's FS module was built 9 seconds later than IOS30, and DI, SDI, OH0, and OH1 were each built 3 minutes and 1 second later than in IOS30, and only seem to differ in the version reported. IOS30 has a newer IOSP from 06/25/07 instead of 06/08/07. Additionally, not all IOS28 modules have $IOSVersion tags (probably only the ones that changed since IOS22), but this was fixed in IOS30.
+
+
Since DI only differs from IOS30 in the heap location, error 001 most likely works in IOS28. The lack of it being enabled is most likely a result of it not being thoroughly tested at the time IOS28 was built.
+
+
IOSP was updated for the first time since [[IOS11]]; IOS11's IOSP was built on 10/25/2006, while IOS28's IOSP was built on 6/8/2007. While no build dates are present in older IOSes for ES, FS, and SDI, it can be assumed that they followed a similar pattern of not updating because [[3.3rev03]] had identical copies of these modules for all IOSes between IOS11 and IOS22. DI followed a similar trend, although it was also not updated between [[IOS9]] and [[IOS11]].

The [[SSL]] module in IOS28 has been given PID 16. Previously, SSL shared PID 15 with the [[Broadway]] IPC calls.
