# 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 and sceUserServiceInitialize2](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - event delivery has no background service thread, so the confirmed priority and Initialize2 CPU affinity mask do not affect host scheduling.
- [sceUserServiceGetUserColor](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - the profile colour corresponds to user index (0: blue, 1: red, 2: green, 3: pink); colours 1, 2 and 3 are assumed, not measured
- [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 up to 4 users ("Player", "Player2", "Player3", "Player4") are supported; user names "Player2", "Player3" and "Player4" are assumed, not measured
- [sceUserServiceGetEvent](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - login and logout events queued dynamically on controller hotplug have no source and are assumed, not measured
- [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
- [sceUserServiceGetKeyboardType, sceUserServiceGetJapaneseInputType, sceUserServiceGetTraditionalChineseInputType](../../../core/libs/prx/libSceUserService/Export.cpp) (libSceUserService) - AnyPS5 stores no per-user keyboard setting, so the initial user reports the keyboard type of the configured system language (`ANYPS5_LANGUAGE`, English US by default) and 0 for the two input variants, and any other user id returns `USER_SERVICE_ERROR_UNKNOWN_USER`. The language-to-keyboard-type table is the repository owner's (languages 0 to 29); a valid language outside it, such as Ukrainian (30), reports 20 (US English). A value that is not a console language number is rejected by `sceSystemServiceParamGetInt` with an error naming `ANYPS5_LANGUAGE`; the call throws it and leaves the output untouched. The input variant is 0 because the owner's table gives 0 for Japanese and Traditional Chinese, the only languages needing one. `sceConvertKeycodeGetImeKeyboardType` consumes these values.
