[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.

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 output being copied to the output buffer.

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.

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.

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
