ES (E-Ticket Services) is the IOS module that is notably responsible for title management, bootstrapping the Broadway, and giving it access to title contents.

This module is always part of the main, bootable binary, along with the IOS kernel, crypto code (IOSC) and the flash filesystem driver (FFS). It runs with more privileges than any other process and has access to most syscalls.

Along with the rest of IOS, this is generally considered a "private interface" -- game developers never call any of these functions directly.

Most of these are now implemented in libogc. Please feel free to submit patches to implement the remaining functions.

ES generally does not launch PPC titles with ES_LaunchTitle; instead, it writes the title information to /sys/launch.sys, then reloads into the requested IOS (even if it is the same IOS), and the new IOS sees /sys/launch.sys when it boots and launches the title, deleting the file and replacing it with /sys/space.sys.

ES is also notable for having the most IOS exploits, some directly affecting title installation, and others allowing for arbitrary code execution.

Commands

Command Name Notes
0x1 Open ES keeps track of three contexts, one per active handle, so only three handles can be opened at once. -1016 will be returned if the maximum amount of handles is exceeded.
0x2 Close -
0x3 Read Not supported; returns IPC_EINVAL (-4).
0x4 Write Not supported; returns IPC_EINVAL (-4).
0x5 Seek Not supported; returns IPC_EINVAL (-4).
0x6 Ioctl Not supported; returns IPC_EINVAL (-4).
0x7 Ioctlv Up to 0x45 ioctlvs available depending on the version.

Calling this IOCTL changes the title permissions to that of the title in the TMD, including verification of the TMD, but does not launch any code. Homebrew can therefore set its permissions to that of any title, or, if this IOS supports fakesigning, anything.

Error codes

This list of ES error codes should be complete for IOS59. Other codes that can technically be returned, but only indirectly (since ES makes use of the FS module and IOSC) are not included in an exhaustive manner in this list.

Error code Notes
-106 (FS) No such file or directory (returned by the FS module indirectly)
-1005 (ES) Invalid public key type in certificate
-1009 (ES) Read failure (short read)
-1010 (ES) Write failure (short write)
-1012 (ES) Invalid signature type (for signed blobs)
-1016 (ES) Maximum amount of handles exceeded (3 handles, as there are only 3 contexts)
-1017 (ES) Invalid arguments
-1020 (ES) Device ID mismatch. Returned by ES_ImportTicket if the ticket is personalised and the device ID from the ticket mismatches with the actual ID.
-1022 (ES) Imported content hash does not match with the hash from the TMD. Returned by ES_ImportContentEnd and ES_ImportBoot.
-1024 (ES) Memory allocation failure
-1026 (ES) Incorrect access rights (according to the TMD)
-1027 (ES) Issuer not found in the certificate chain
-1028 (ES) Ticket not found
-1029 (ES) Invalid ticket. This is returned if the common key field contains an invalid value (anything other than 0 or 1). This is also returned from ES_LaunchTitle if the title ID contained in the ticket does not match the TMD title ID.
-1031 (ES) During LaunchTitle/ImportTitle: installed boot2 version is too old.

During ImportBoot: downgrades are not allowed.

-1032 (ES) Fatal error early in ES initialisation. Can also be returned in ES_CheckHasKoreanKey in some cases. [check]
-1033 (ES) A ticket limit was exceeded (duration or launch count)
-1034 (ES) Returned in ES_CheckHasKoreanKey in some cases. [check]
-1035 (ES) A title with a higher version is already installed
-1036 (ES) Required sysversion(IOS) is not installed (only for the system menu [check])
-1037 (ES) Installed number of contents doesn't match TMD (only for the system menu [check])
-1039 (DI) Returned by DI as an ES error code when "TMD not supplied for disc/nand game"
-2000 (IOSC) Permission denied (returned when accessing an object for which the caller has no permission)
-2001 (IOSC) IOSC_EEXIST
-2003 (IOSC) IOSC_EMAX
-2004 (IOSC) IOSC_ENOENT
-2005 (IOSC) IOSC_INVALID_OBJTYPE

-2009 (IOSC) IOSC_INVALID_VERSION
-2010 (IOSC) IOSC_INVALID_SIGNER
-2011 (IOSC) IOSC_FAIL_CHECKVALUE

Known to be returned when a signature check failed.

-2012 (IOSC) Internal failure
-2013 (IOSC) Memory allocation failure. Known to be returned when the keyring is full (contains 0x20 keys)
-2014 (IOSC) Invalid size
-2015 (IOSC) Invalid address
-2016 (IOSC) Unaligned data
