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.
