Imp Uhrfik Simone: /* Colors */ ...verified and added Hex-Values for Newly Released Pastel Colored Joy-Con (...Pastel-Pink, Pastel-Yellow, Pastel-Purple, & Pastel-Green)

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

= Hardware =
The controllers themselves are simple to disassemble and identify.

= Firmware =
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

= Protocol =
The Joy-Con can communicate wirelessly over Bluetooth or through the rails over UART. This uses a Nintendo proprietary protocol called "Nwcp".

== Left & Right Separate Joy-con ==
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

= Protocol =
The Joy-Con can communicate wirelessly over Bluetooth or through the rails over UART. This uses a Nintendo proprietary protocol called "Nwcp".

== Left & Right Separate Joy-con ==
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2023-04-29T10:15:29Z

Imp Uhrfik Simone: /* Colors */ ...just removed the KATAKANA suffix of the word "edition" to align with other Japanese titles (...as "edition" was also omitted in Japanese from all other previous titles)

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

= Hardware =
The controllers themselves are simple to disassemble and identify.

= Firmware =
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

== Left & Right Separate Joy-con ==
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

= Hardware =
The controllers themselves are simple to disassemble and identify.

| Orange || STMicroelectronics NFCBEA 812006 33 (Likely NFC reader IC)
|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

= Firmware =
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

= Protocol =
The Joy-Con can communicate wirelessly over Bluetooth or through the rails over UART. This uses a Nintendo proprietary protocol called "Nwcp".

== Left & Right Separate Joy-con ==
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

HID Input Report Descriptor (Hexadecimal):

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

= Hardware =
The controllers themselves are simple to disassemble and identify.

|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

= Firmware =
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

= Protocol =
The Joy-Con can communicate wirelessly over Bluetooth or through the rails over UART. This uses a Nintendo proprietary protocol called "Nwcp".

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

Imp Uhrfik Simone: /* Colors */ ...preliminary addition of Splatoon 3 joy-con ...will follow-up once hex-colors are vetted ...also added special edition consoles with "retail color" joy-con

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

= Hardware =
The controllers themselves are simple to disassemble and identify.

|-

|}

= Firmware =
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

= Protocol =
The Joy-Con can communicate wirelessly over Bluetooth or through the rails over UART. This uses a Nintendo proprietary protocol called "Nwcp".

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

Imp Uhrfik Simone: /* Colors */ ...added release dates ...Neon-Green/Neon-Pink release-dates specifically referenced from official Nintendo website (www.nintendo.co.jp) ...not using US release date

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

=== Left & Right Separate Joy-con ===
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2021-10-20T13:29:17Z

Imp Uhrfik Simone: /* Colors */

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

|-
| Orange || STMicroelectronics NFCBEA 812006 33 (Likely NFC reader IC)
|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}
The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

=== Left & Right Separate Joy-con ===
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}
The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2021-07-18T12:12:22Z

Imp Uhrfik Simone: /* Colors */ ...White Joy-Con Place-Holder Hex Values (...until actual White Jo-Con Hex Values are known)

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

=== Left & Right Separate Joy-con ===
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

=== Left & Right Separate Joy-con ===
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2021-06-04T23:45:01Z

Imp Uhrfik Simone: /* Colors */

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

|-

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2021-06-04T23:43:46Z

Imp Uhrfik Simone: /* Colors */

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}
The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

== Colors ==
HEX codes for the colors shown in the "Controllers" menu of the Switch UI can be found in a Joy-con SPI dump starting at offset 0x6050. Body color is first followed by button color and each is 3 bytes long. These values are able to be re-written with any HEX color value to make the Joy-cons show up as different colors in the UI. The following is a list of official HEX colors recovered from SPI dumps.

Joy-Con

2021-06-04T23:31:30Z

Imp Uhrfik Simone: /* Colors */

Joy-Con is the name for the Switch's primary game controllers. The controllers communicate to the console through bluetooth and can be disconnected from the main unit.

== Hardware ==
The controllers themselves are simple to disassemble and identify.

|-
| Orange || STMicroelectronics NFCBEA 812006 33 (Likely NFC reader IC)
|-
| Yellow|| Macronix International MX25U4033E 4 Mb CMOS Flash
|}

== Firmware ==
''See also: [[Joy-Con Firmware]]''

The firmware of the Joy-Cons seems to be generic across all instances. Details such as the handedness of the controller and the color is just indicated in a configuration part of the flash. Judging by quick glance at the firmware, it's probably identical to that used on the Pro Controller as well.

|-
| Joy-Con Left (Blue) || [[:File:pad.L.bin|flash dump]]
|-
| Joy-Con Right (Red) || [[:File:pad.R.bin|flash dump]]
|}
The flash is in a patch-ram format. Tools for dealing with it are available [https://github.com/shuffle2/nxpad].
A dump of the ROM region (taken while firmware was running) can be found [[:File:bcm20734_rom.bin|here]]. Note this is the same SoC used on the other controller models, as well.

=== Left & Right Separate Joy-con ===
When paired directly to a computer over bluetooth, the joy-con both provide identical HID input report descriptor. This does not appear to include motion controls, IR data, or NFC. They both behave as detached single-player controllers.
