This is "nn::settings::ISettingsServer".

Cmd	Name	Notes
0	GetLanguageCode	No input, returns an output #LanguageCode. This is the current system language.
1	GetAvailableLanguageCodes	Takes a type-0xA buffer containing the #LanguageCode output array, returns an output s32.
2	[4.0.0+] MakeLanguageCode	Takes an input #Language, returns an output #LanguageCode.
3	GetAvailableLanguageCodeCount	No input, returns an output s32.
4	GetRegionCode	No input, returns a #RegionCode.
5	[4.0.0+] GetAvailableLanguageCodes2	Takes a type-0x6 buffer containing the #LanguageCode output array, returns an output s32.
6	[4.0.0+] GetAvailableLanguageCodeCount2	No input, returns an output s32.
7	[4.0.0+] #GetKeyCodeMap
8	[5.0.0+] GetQuestFlag	Identical to "set:sys" GetQuestFlag.
9	[6.0.0+] GetKeyCodeMap2
10	[9.0.0+] #GetFirmwareVersionForDebug

[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.

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 output being copied to the output buffer.

Language

"nn::settings::Language" (s32) is basically array indices in the output array from GetAvailableLanguageCodes.

LanguageCode

This is "nn::settings::LanguageCode".

This is an u64, which is a NUL-terminated string.

RegionCode

A region code is a signed 32-bit value representing a particular region. Currently the available regions defined by the system are as follows:

Value	Region
0	Japan
1	USA
2	Europe
3	Australia
4	China
5	Korea
6	Taiwan
Any other value	Considered an unknown region

GetEciDeviceCertificate

Takes a type-0x16 output buffer with fixed size 0x180.

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

Returns the ETicket certificate (RSA signed).

GetSslKey

Takes a type-0x16 output buffer with fixed size 0x134.

Takes a type-0x16 output buffer with fixed size 0x804.

Returns a container with the plaintext SSL certificate.

Used by SSL-sysmodule, see here.

GetGameCardKey

[5.0.0+] Now returns an additional 4-bytes.

GetEticketDeviceKey

Takes a type-0x16 output buffer with fixed size 0x244.

Returns the extended ETicket RSA-2048 key (0x240 bytes) from CAL0. If the extended key is not programmed then it falls back to the normal ETicket RSA-2048 key (0x220 bytes).

GetEciDeviceCertificate2

Same as #GetEciDeviceCertificate, but returns a RSA-2048 variant of the device certificate.

GetEciDeviceKey2

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.

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.

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.

GetProductModel

No input, returns an output s32.

GetMiiAuthorId

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

Returns an u32 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

Takes an input s32 #KeyboardLayout, no output.

GetAllowedSslHosts

Takes a type-0x6 output buffer, returns an output s32. This buffer contains an array of 0x8-byte "nn::settings::system::AllowedSslHost" entries.

GetRebootlessSystemUpdateVersion

No input, returns an output #RebootlessSystemUpdateVersion.

GetQuestFlag

Gets a flag determining whether the console is a kiosk unit (codenamed "Quest"). Used by qlaunch to determine whether to launch Retail Interactive Display Menu.

GetDataDeletionSettings

No input, returns an output #DataDeletionSettings.

SetDataDeletionSettings

Takes an input #DataDeletionSettings, no output.

GetWirelessCertificationFileSize

No input, returns an output u64 size.

GetWirelessCertificationFile

Takes a type-0x6 output buffer, returns an output u64 size.

This gets the WirelessCertificationFile.

SetRegionCode

Takes an input s32 #RegionCode, no output.

GetChineseTraditionalInputMethod

No input, returns an output s32 #ChineseTraditionalInputMethod.

SetChineseTraditionalInputMethod

Takes an input s32 #ChineseTraditionalInputMethod, no output.

GetHomeMenuScheme

No input, returns an output 0x14-byte struct "nn::settings::system::HomeMenuScheme".

This struct contains 5 RGBA8 u32s for colors: Main, Back, Sub, Bezel and Extra.

The colors are loaded from Calibration, with the set of fields to use selected by ColorVariation. When ColorVariation is invalid (must be 1-4), the following fixed color values are returned: 0xFF323232, 0xFF323232, 0xFFFFFFFF, 0xFFFFFFFF, 0xFF000000.

GetT

No input, returns an output u8 bool IsT.

[9.0.0+] This is a wrapper for #GetPlatformRegion: IsT = (PlatformRegion == 2).

SetT

Takes an input u8 bool IsT, no output.

[9.0.0+] This is a wrapper for #SetPlatformRegion: PlatformRegion = 1 + (IsT & 1).

GetPlatformRegion

No input, returns an output s32.

SetPlatformRegion

Takes an input s32, no output.

GetHomeMenuSchemeModel

No input, returns an output u32.

Loads the 0xB-byte setting <"settings_debug", "home_menu_scheme_model">, throwing an error if loading this fails. Depending on the content of the setting, the output u32 is either determined by the value of this setting, or loaded from Calibration.

GetMemoryUsageRateFlag

No input, returns an output u8 bool.

GetTouchScreenMode

No input, returns an output s32.

Official sw loads the output as an u8 and copies it to an output #TouchScreenMode.

SetTouchScreenMode

Takes an input s32, no output.

Official sw sets the input to an u8 loaded from an input #TouchScreenMode.
