=== 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.  
  
The Title ID of the IOSes follow this convention "00000001-000000xx" where xx is the IOS number in hexadecimal.
+
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 [[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''.
  
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.
+
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''.
  
As of late 2008, Nintendo has been replacing some versions of IOS with "stubs" -- small IOSes that do not seem to be functional.  This is most likely an attempt to prevent vulnerable versions of IOS from being installed (see e.g. IOS254).

| 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.

| Contains NAND BOOT PROGRAM (AKA NANDloader) - this was probably accidental. It was probably intended to be put in IOS21, but a miscommunication over whether "1-15" was in decimal or hex caused it to end up here, as [[4.3]] removed the tool from IOS15 but not IOS21.

| Initially used by the [[Wii Backup Disc]]. The version on the [[Wii Backup Disc]] was infamously used by pirates, until [[4.0|System Menu 4.0]] mothballed this IOS as of v512. The mothballed stub version [https://wii.marcan.st/wiimpersonator/reports/wii/KOR/20090327-080013.log was retracted] from the Korean SOAP server 2 days after [https://wii.marcan.st/wiimpersonator/reports/wii/KOR/20090325-100223.log its original posting] for unknown reasons. The [[4.1|System Menu 4.1]] update for Korea [https://wii.marcan.st/wiimpersonator/reports/wii/KOR/20090730-041014.log added it back], along with stubbing IOS52.

Latest revision as of 17:40, 19 November 2021

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, 2.1, 2.4, 2.6, 2.8, 2.9, 3,10, 4.10, 5.10, 105.10 v1, v513, v516, v518, v520, v521, v778, v1034, v1290, v26890 Has only one LED pattern: blinking. Used by System Menu 1.0 and launch games. v513 is a lost pre-release version. 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 ?, 3.0 ?, 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. Also used by the second version of Forecast Channel dummy and News Channel dummy, although these could never be launched. v10, v15, v16, v273, v1031, v1032 Active
IOS14 1.1, 1.6, 1.7, 2.8, 4.7, 4.8, 5.8, 105.8 v257, v262, v263, v520, v1031, v1032, v1288, v26888 v262, v263, v520, v1031, v1032 Active
IOS15 1.1, 1.2, 1.3, 1.4, 1.9, 1.10, 2.11, 4.7, 4.8, 5.8, 105.8 v257, v258, v259, v260, v265, v266, v523, v1031, v1032, v1288, v26888 Contains NAND BOOT PROGRAM (AKA NANDloader) - this was probably accidental. It was probably intended to be put in IOS21, but a miscommunication over whether "1-15" was in decimal or hex caused it to end up here, as 4.3 removed the tool from IOS15 but not IOS21. v257, v258, v259, v260, v265, v266, v523, v1031, v1032 Active
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
IOS17 2.0, 2.5, 2.6, 3.7, 4.7, 4.8, 5.8, 105.8 v512, v517, v518, v775, v1031, v1032, v1288, v26888 v512, v517, v518, v775, v1031, v1032 Active
IOS20 0.12, 1.0 v12, v256 Feb 22 2007 04:25:59. Used by System Menu 2.2. v12, v256 Mothballed

False positives

These IOS versions may be displayed by tools such as SysCheck, but are not actual IOSes.

Apparent name Real name Purpose
IOS0 ES_Identify Superuser This TMD is automatically installed when it is passed to ES_Identify, but its real purpose is to give superuser permissions to the ES_Identify caller.
IOS1 boot2 glitch This appears when something is installed into /title/00000001/00000001. This directory is normally unused, as 1-1 is reserved for boot2, but some homebrew (and possibly Dolphin) may incorrectly install it into this directory.
IOS2 System Menu This will not show in most tools, but the System Menu uses ID 1-2, which may look like an IOS to a very basic tool.
IOS512 BC-NAND Some tools released before the vWii may not know about BC-NAND and BC-WFS, which are used as ancast images to launch NAND and WFS titles respectively.
IOS513 BC-WFS See IOS512
