# 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`
- [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
