# libSceUserService technical debt

### Unknown function info

- [sceUserServiceGetNpAccountId](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - the account id for a user with no linked PSN account is assumed to be 0 with success; libSceNpManager's `sceNpGetAccountIdA` answers the same question with `SCE_NP_ERROR_SIGNED_OUT`
- [sceUserServiceInitialize, sceUserServiceTerminate](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - measured on a PS5 (firmware 13.60): before `sceUserServiceInitialize`, and again after `sceUserServiceTerminate`, `sceUserServiceGetLoginUserIdList`, `sceUserServiceGetEvent` and `sceUserServiceTerminate` return `0x80960002`; a second initialization returns `0x80960003`, and a new initialization reports the login of the initial user again. The other calls were not measured before initialization and do not check it. `sceUserServiceInitialize2` was not measured: it initializes like `sceUserServiceInitialize` and returns success when already initialized
- [sceUserServiceGetUserColor](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - the default profile colour is assumed to be blue (0)
- [sceUserServiceGetUserName](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - `0x80960105`, which a PS5 (firmware 13.60) returns for a user id it does not know, has no known name; it is `USER_SERVICE_ERROR_UNKNOWN_USER` here. On the console a registered user who is not logged in still gets their name; here only the initial user exists
- [sceUserServiceGetAgeLevel](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - on a PS5 (firmware 13.60) the value is the age set in the user's parental restriction (0, 7, 12 and 15 were measured) and `0xFFFFFFFF` without one; a user who is not logged in returns `0x80960009` with or without an output. Parental restrictions are not modelled, so the initial user is always reported as unrestricted. PPSA12544 (Unity) only stores the value for its user profile
- [sceUserServiceGetAccessibilityChatTranscription, PressAndHoldDelay, TriggerEffect, Vibration, ZoomEnabled, ZoomFollowFocus](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - report 0, 0, 1, 1, 0 and 1, what a PS5 (firmware 13.60) reports for a user whose accessibility settings are all at their defaults; the console reports the user's own settings (a changed vibration intensity read 3), which are not modelled. What each number means is unknown. A user who is not logged in returns `0x80960009` with or without an output
- [sceUserServiceGetAccessibilityKeyremapEnable, sceUserServiceGetAccessibilityZoom](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - declared without parameters as throwing stubs calling `NotImplemented_nid_no_patch`. Their signatures and values remain unverified on hardware
