BunnyFl ran firmware 13.42's libSceSystemService.sprx in an emulator and
recorded the checks these calls make before they pass a request on. A
null title ID or one whose length isn't 9 makes sceSystemServiceGetAppId
and sceLncUtilGetAppId return -1 and sceLncUtilIsAppLaunched return
0x80940005. A null output, list, count or user returns 0x80940005 from
the LncUtil and SystemService calls and 0x80e30003 from
sceShellCoreUtilGetUserFocus, before the app ID is looked at, and a null
sceLncUtilLoadExec path returns 0x80940005.
What the module passes on as a request still throws: another
9-character title ID, another app ID, a list capacity of 0 and an empty
sceLncUtilLoadExec path.
Inside Gran Turismo 7 on a PS5 (firmware 13.40) parameters 7 (game parental level) and 1000 (enter button assignment) returned 0x80A10003 like every other unknown parameter; 1 to 5, 100 and 400 answered.
SystemServiceConsoleLanguage in SystemService.hpp reads ANYPS5_LANGUAGE
with the same default, range and error as sceSystemServiceParamGetInt,
which now calls it. Other libraries can pick the console language
without linking libSceSystemService.
sceSystemServiceParamGetInt always reported English (United States) as
the console language, so a title that follows the console's language,
such as Jelly5 (PPSA99505) with its Arabic text, can only show English.
ANYPS5_LANGUAGE now selects a console language number from 0 to 30
(21 is Arabic). Unset or empty keeps English (United States); any other
value throws at the language query instead of being ignored.
(cherry picked from commit 9bcf196daa01b07a22be876a7f1143149503e054)
Report an app ID for the running title from sceSystemServiceGetAppIdOfRunningBigApp, and shut the guest down and exit when sceSystemServiceKillApp receives that ID with the arguments -1, 0 and 0. SwanStationPS5 (PPSA98510) 1.0.6 closes itself this way and stops on both imports on main.
The export threw, and titles query the system name during startup.
Parameter 6 (the system name) now writes the fixed name "PS5" into a
buffer of at least SYSTEM_SERVICE_MAX_SYSTEM_NAME_LENGTH (65) bytes.
A null buffer or a zero size returns SYSTEM_SERVICE_ERROR_PARAMETER,
as in KytyPS5. Other parameter ids and buffers of 1 to 64 bytes still
throw, because no PS5 source gives their result. guest_system_service
covers the error rows, both throws and the returned name.
