[4.0.0+] Official user-processes now use GetAvailableLanguageCodes2/GetAvailableLanguageCodeCount2 instead of {original commands}.

In official user-processes in the [[#Language]]->[[#LanguageCode]] conversion function (MakeLanguageCode):
* During one-time init, GetAvailableLanguageCodes is used to initialize the LanguageCodes array cache, with max_entries=0xF (buffer size in u64s). [4.0.0+] GetAvailableLanguageCodes2 is now used with max_entries 0x40.
* [4.0.0+] When the input [[#Language]] is larger than the cached total_entries from the above command output, or [[#Language]] is negative, command MakeLanguageCode is used instead of the array.

== GetLanguageCode ==
No input, returns an output [[#LanguageCode]]. This is the current system language.

== GetAvailableLanguageCodes ==
Takes a type-0xA buffer containing the [[#LanguageCode]] output array, returns an output s32.

== MakeLanguageCode ==
Takes an input [[#Language]], returns an output [[#LanguageCode]].

== GetAvailableLanguageCodeCount ==
No input, returns an output s32.

== GetRegionCode ==
No input, returns a [[#RegionCode_2|RegionCode]].

== GetAvailableLanguageCodes2 ==
Takes a type-0x6 buffer containing the [[#LanguageCode]] output array, returns an output s32.

== GetAvailableLanguageCodeCount2 ==
No input, returns an output s32.

== GetKeyCodeMap ==
Takes a type-0x16 output buffer containing KeyCodeMap, official sw uses fixed size 0x1000. This is probably related to HID keyboard.

== GetFirmwareVersionForDebug ==
Takes a type-0x16 output buffer containing a 0x80-byte "nn::oe::FirmwareVersionForDebug".

This uses [[#GetDebugModeFlag]] internally, if the output flag is 0 an error is thrown.

This runs the same code as GetFirmwareVersion2, with the last 0x80-bytes of the [[System_Version_Title|output]] being copied to the output buffer.

== GetConfigurationId1 ==
Returns the [[#ConfigurationId1]].

== GetEciDeviceCertificate ==
Takes a type-0x16 output buffer containing a [[#EccB233DeviceCertificate]].

Returns the device certificate (ECC signed). This is identical to 3DS DeviceCert/CTCert besides the strings. NIM loads the DeviceId from this.

== GetEticketDeviceCertificate ==
Takes a type-0x16 output buffer containing a [[#Rsa2048DeviceCertificate]].

Returns the ETicket certificate (RSA signed).

== GetSslKey ==
Takes a type-0x16 output buffer containing a [[#SslKey]].

Returns the extended SSL key (0x130 bytes) from [[Calibration#CAL0|CAL0]]. If the extended key is not programmed then it falls back to the normal SSL key (0x110 bytes).

Used by SSL-sysmodule, see [[SSL_services|here]].

== GetSslCertificate ==
Takes a type-0x16 output buffer containing a [[#SslCertificate]].

Used by SSL-sysmodule, see [[SSL_services|here]].

== GetGameCardKey ==
Takes a type-0x16 output buffer containing a [[#GameCardKey]].

Official user-processes gets a new service session handle each time a set:sys cmd is used, with the session being closed afterwards.

== SetLanguageCode ==
Takes an input [[#LanguageCode]], no output.

== GetFirmwareVersion ==
Takes a type-0x1A output buffer. User-processes use hard-coded size 0x100.

If needed, reads the content of the [[System_Version_Title]] "/file" into state. This is only done once.

Then the above 0x100-byte data is copied to the output buffer.

== GetAccountSettings ==
No input, returns an output [[#AccountSettings]].

== SetAccountSettings ==
Takes an input [[#AccountSettings]], no output.

== GetEulaVersions ==
Takes a type-0x6 output buffer containing an array of [[#EulaVersion]], returns an output s32 total_out.

== SetEulaVersions ==
Takes a type-0x5 input buffer containing an array of [[#EulaVersion]], no output.

== GetColorSetId ==
No input, returns an output s32.

This is the current Theme set by System Settings.

* 0: "Basic White"
* 1: "Basic Black"

== SetColorSetId ==
Takes an input s32, no output.

== GetNotificationSettings ==
No input, returns an output [[#NotificationSettings]].

== SetNotificationSettings ==
Takes an input [[#NotificationSettings]], no output.

== GetAccountNotificationSettings ==
Takes a type-0x6 output buffer containing an array of [[#AccountNotificationSettings]], returns an output s32 total_out.

== SetAccountNotificationSettings ==
Takes a type-0x5 input buffer containing an array of [[#AccountNotificationSettings]], no output.

== GetSettingsItemValue ==
Takes two type-0x19 input buffers and a type-0x6 output buffer. Returns an output u64 for the actual size written to the outbuf.

The outbuf_size is compared with the config_size. When config_size is larger than outbuf_size, outbuf_size is used for the memcpy, otherwise config_size is used. Afterwards the size used for the memcpy is written to output(see above).

If loading from main config fails, it will also attempt to load config from various state if the input strings match hard-coded strings.

== GetTvSettings ==
No input, returns an output [[#TvSettings]].

== SetTvSettings ==
Takes an input [[#TvSettings]], no output.

== GetDebugModeFlag ==
Returns an output u8.

Loads the 1-byte config for <"settings_debug", "is_debug_mode_enabled">. If that fails, value 0x1 is written to output. This uses the same func as ReadSetting internally.

Returned retval is always 0.

== GetPrimaryAlbumStorage ==
No input, returns an output s32 [[#PrimaryAlbumStorage]].

== SetPrimaryAlbumStorage ==
Takes an input s32 [[#PrimaryAlbumStorage]], no output.

== GetBatteryLot ==
No input, returns an output [[#BatteryLot]].

== GetSerialNumber ==
Returns the 0x18-byte SerialNumber string.

== GetSleepSettings ==
No input, returns an output [[#SleepSettings]].

== SetSleepSettings ==
Takes an input [[#SleepSettings]], no output.

== GetInitialLaunchSettings ==
No input, returns an output [[#InitialLaunchSettings]].

== SetInitialLaunchSettings ==
Takes an input [[#InitialLaunchSettings]], no output.

== GetDeviceNickName ==
Takes a type-0x16 output buffer containing a [[#DeviceNickName]].

With [10.1.0+] sdknso now uses the set cmd instead of the setsys cmd.

== SetDeviceNickName ==
Takes a type-0x15 input buffer containing a [[#DeviceNickName]].

== GetProductModel ==
No input, returns an output s32.

== GetMiiAuthorId ==
No input, returns an output "nn::util::Uuid".

== GetServiceDiscoveryControlSettings ==
Returns an u32 [[#ServiceDiscoveryControlSettings|ServiceDiscoveryControlSettings]].

== GetErrorReportSharePermission ==
No input, returns an output s32 [[#ErrorReportSharePermission]].

== SetErrorReportSharePermission ==
Takes an input s32 [[#ErrorReportSharePermission]], no output.

== GetAppletLaunchFlags ==
No input, returns an u32 bitmask [[#AppletLaunchFlag]].

== SetAppletLaunchFlags ==
Takes an input u32 bitmask [[#AppletLaunchFlag]], no output.

== GetKeyboardLayout ==
No input, returns an output s32 [[#KeyboardLayout]].

== SetKeyboardLayout ==
