The Title ID of the IOSes follow this convention "00000001-000000xx" where xx is the IOS number in hexadecimal.

The "IOS number" is best thought of as a "Major" version number for the firmware, and probably corresponds to a specific version of Nintendo's (proprietary) SDK. For example, the version of the SDK used to compile Zelda: Twilight Princess probably was tailored to run on IOS9.

In general, IOSx0 is used for the system menu (IOS20, IOS30, IOS40, IOS50, IOS60, IOS70). IOSx1 seems to be used for Nintendo channels (e.g. IOS31, IOS51, IOS61).

Each IOS has a 16-bit '''version number''' in its TMD. This version number is seen in decimal form in the filenames of IOS WADs on update partition (e.g. "IOS9-64-v516.wad" for version 516 (decimal)). Converted to hex, that 516 becomes 0x0204, and can be read as "2.4" -- IOS9, version 2.4.

As a rule, an existing IOS will never have new features added to it, to protect binary compatibility. This means that any updates for existing IOSes are only meant to fix bugs (generally, security bugs).

=== Future of IOS ===
+
=== Stubs ===
−
As of late 2008, Nintendo has been replacing some versions of IOS with small non-functional "place holder" IOSes. This is to prevent the reuse of the IOS "slot" for software other than official Nintendo Software which utilized that IOS number.
+
As of [[3.3rev03|late 2008]], Nintendo has been replacing some versions of IOS with small non-functional [[stub IOS|stub IOSes]]. This is so that they do not need to port security fixes to unused IOS slots, or in some cases, prevent [[IOS16|private IOSes]] from being leaked and installed for older exploits, as [[:/dev/es|ES]] refuses to install a title if an already-installed copy has a higher version number. Such IOSes have been marked as ''Mothballed''.
−
Nintendo can come back at a later date if necessary and "reuse" an IOS slot at their own discretion by simply increasing the version number of the title and replacing it with a functional IOS once again. These IOSes have been marked as '''Mothballed''' on the table denoting that they could quite possibly be reused in the future if Nintendo decides to do so.
+
 
 +
A few IOSes above slot 200 were also stubbed in the [[4.2]] update, namely those commonly used by pirates. Nintendo's intentions are unclear, but they seem to have been attempting to overwrite the [[cIOS]]. However, this was trivially bypassed with version 65535 (most stubs, including the anti-cIOS ones, use version 65280). These IOSes have been marked as ''Preventative''.

−
| Despite the version being 0.7.6 as seen in the SDK, the titleid is IOS3. IOS in beta used the IOS0 title id, then as it neared release they changed to IOS3. Later on it changed to IOS4 which is the first one that got shipped at retail. IOS3 is used in the factory and comes preinstalled as a stub on some wiis because of it; later version is a stub. The older version is lost but we know it exists because SDK.
+
| IOS3 is found as a stub on [[RVL-CPU-20]] consoles, and appears to be used by newer versions of the 122E disc. The version number used by 122E is unknown.

| Previous versions only had minimal drivers (lacking KD, WL, WD, SSL), and were used during manufacturing. v3's timestamp is Aug 10, 2006; it was used by the [[Prelaunch System Menu]] present on pre-launch kiosk Wiis that shipped without a full System Menu. v259 was used on Korean Wiis at some point, although it is unknown what, if any, purpose it served. v1's existence is known through remnants in the Startup Disc NAND. v65280 is a stub; at one point, v3 was on CDN, likely by accident, but it was replaced with the stub version.

 This article is outdated. Please refer to the individual IOS pages (e.g. IOS37) for more up-to-date information.

This page is intended to track changes in IOS (the operating system that runs on Starlet) such as: added features, bug fixes, etc. It will also cover what different minor versions are known to exist.

Overview

The Title ID of the IOSes follow this convention "00000001-000000xx" where xx is the IOS number in hexadecimal. The "IOS number" is best thought of as a "Major" version number for the firmware, and probably corresponds to a specific version of Nintendo's (proprietary) SDK. For example, the version of the SDK used to compile Zelda: Twilight Princess probably was tailored to run on IOS9.

In general, IOSx0 is used for the system menu (IOS20, IOS30, IOS40, IOS50, IOS60, IOS70). IOSx1 seems to be used for Nintendo channels (e.g. IOS31, IOS51, IOS61).

Each IOS has a 16-bit version number in its TMD. This version number is seen in decimal form in the filenames of IOS WADs on update partition (e.g. "IOS9-64-v516.wad" for version 516 (decimal)). Converted to hex, that 516 becomes 0x0204, and can be read as "2.4" -- IOS9, version 2.4.

As a rule, an existing IOS will never have new features added to it, to protect binary compatibility. This means that any updates for existing IOSes are only meant to fix bugs (generally, security bugs).

Stubs

As of late 2008, Nintendo has been replacing some versions of IOS with small non-functional stub IOSes. This is so that they do not need to port security fixes to unused IOS slots, or in some cases, prevent private IOSes from being leaked and installed for older exploits, as ES refuses to install a title if an already-installed copy has a higher version number. Such IOSes have been marked as Mothballed.

A few IOSes above slot 200 were also stubbed in the 4.2 update, namely those commonly used by pirates. Nintendo's intentions are unclear, but they seem to have been attempting to overwrite the cIOS. However, this was trivially bypassed with version 65535 (most stubs, including the anti-cIOS ones, use version 65280). These IOSes have been marked as Preventative.

Version Table

Highlighted versions are not available on NUS.

IOS Number Minor(s) Version Number(s) Notes NUS Availability Status
IOS3 255.0 v65280 IOS3 is found as a stub on RVL-CPU-20 consoles, and appears to be used by newer versions of the 122E disc. The version number used by 122E is unknown. Unavailable Mothballed
IOS4 0.1, 0.3, 1.3, 255.0 v1, v3, v259, v65280 Previous versions only had minimal drivers (lacking KD, WL, WD, SSL), and were used during manufacturing. v3's timestamp is Aug 10, 2006; it was used by the Prelaunch System Menu present on pre-launch kiosk Wiis that shipped without a full System Menu. v259 is a stub found on some Korean Wiis. v1's existence is known through remnants in the Startup Disc NAND. v65280 is a stub; at one point, v3 was on CDN, likely by accident, but it was replaced with the stub version. v65280 Mothballed
IOS5 255.0 v65280 The IOS5 going around the internet is a modded version of IOS21 and is not real, the legit IOS5 will probably never be seen. An IOS with the same title ID exists as a stub on some Wiis, probably for repair discs, much like IOS16 Unavailable Mothballed
IOS9 0.1, 2.4, 2.6, 2.8, 2.9, 3,10, 4.10, 5.10, 105.10 v1, v516, v518, v520, v521, v778, v1034, v1290, v26890 Has only one LED pattern: blinking. Used by System Menu 1.0 and launch games. Version 1's internal timestamp is Aug 22 2006 13:46:28. v518 was at some point found on Korean Wiis. v520, v521, v778, v1034 Active
IOS10 2.6, 3.0 v518, v768 Used by the Japanese version of System Menu 1.0. Fixed an AOSS bug that was in IOS9. v768 Mothballed
IOS11 0.10, 1.0 v10, v256 Internal timestamp says Nov 14 2006 16:26:01. Used by System Menu 2.0 and 2.1. v10, v256 Mothballed
IOS12 0.6, 0.11, 0.12, 1.13, 2.13, 2.14, 3.14, 13.14 v6, v11, v12, v269, v525, v526, v782, v26382 This IOS has an internal date of June 4, 2006; this would make it the earliest known IOS, although it is likely that IOS9 came first due to its lower slot number, but the older IOS9 was unreleased. v6, v11, v12, v269, v525, v526 Active
IOS13 0.10, 0.15, 0.16, 1.11, 4.7, 4.8, 5.8, 105.8 v10, v15, v16, v273, v1031, v1032, v1288, v26888 Used by Photo Channel and Photo Channel 1.1.

IOS16 1.1, 2.0 v257, v512 Initially used by the Wii Backup Disc. The version on the Wii Backup Disc was infamously used by pirates, until System Menu 4.0 mothballed this IOS as of v512. The mothballed stub version was retracted from the Korean SOAP server 2 days after its original posting for unknown reasons. The System Menu 4.1 update for Korea added it back, along with stubbing IOS52. v512 Mothballed
