IOS15 was previously used by some official channels; it has not been stubbed because the Internet Channel, which could not be updated through standard updates, previously used it.
This IOS contains the NAND Boot Program; it seems to be a slightly modified version of v1.21 that patches the Internet Channel. This version is loaded whenever HADJ, HADE, or HADP is loaded, and the content itself is located by searching for the first content with more than 0x400 bytes. This code is only capable of loading private contents, which is why the boot program is not in /shared1.
In the past, this IOS was often used by homebrew, as it is one of the only known IOSes that is safe to downgrade on RVL-CPU-20 Wiis. It was then used to patch the signing bug back into newer IOSes, like IOS36.
The only difference between IOS14v257 and IOS15v257 is that the NCD version changed; this was most likely to allow IOS15 to be updated without causing problems with Pokémon Battle Revolution.
Titles using this IOS
None of the latest versions of these titles use IOS15.
Version history
| Version | Signing bug? | /dev/flash access? | ES_Identify? | STM Release Exploit? | STM IOCTL overflow? | SDI register index bug? | Notes |
|---|---|---|---|---|---|---|---|
| v257 | Yes | Yes | Yes | Yes | Yes | Yes | First release |
| v258 | Yes | Yes | Yes | Yes | Yes | Yes | Added NAND Boot Program, and updated Starlet code to load it when launching the Internet Channel. |
| v259 | Yes | Yes | Yes | Yes | Yes | Yes | Removed NAND Boot Program; this version is identical to v257, only with a different build tag. v258 most likely caused errors when the Internet Channel used non-standard IOSes. |
| v260 | Yes | Yes | Yes | Yes | Yes | Yes | Added back NAND Boot Program; compared to v258, the Starlet code now allows any title to be used as the Internet Channel's system version (v258 only allowed 1-3 through 1-255). |
| v265 | No | No | No | Yes | Yes | Yes | 3.3rev03 update. This version of IOS15 uses the same version of ES as other IOSes, so the NAND Boot Program is no longer loaded, despite still being included. |
