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.

Controller 1.0.0
Joy-Con Left (Blue) flash dump
Joy-Con Right (Red) flash dump

The flash is in a patch-ram format. Tools for dealing with it are available [3]. A dump of the ROM region (taken while firmware was running) can be found 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.

Color Name Body HEX Button HEX
Gray / グレー #828282 #0F0F0F
Neon Red / ネオンレッド #FF3C28 #1E0A0A
