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.

Array-index / #Language	#LanguageCode	Icon language filename	Name

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

Used for accessing data calibrated at the factory.

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

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.

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.

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 entry count. This buffer contains an array of 0x100-byte "nn::settings::system::AllowedSslHost" entries.

GetRebootlessSystemUpdateVersion
