Updated: Sys-con 0.5.0 Added DualShock 4 support.
Notes of sys-con 0.5.0:
⚠ I can't support your generic 3rd party HID controller yet. It is a limitation of the firmware and I'm looking to work around it.
⚠ If you get the error 2003-0008 (0x1003), you're running too many sysmodules. Disable other memory demanding sysmodules like sys-ftpd or ldn_mitm.
Due to firmware limitations, only one generation of Dualshock 4 can be recognized at a time. If you have a Dualshock 4 model "CUH-ZCT2E", you need to go to sdmc:/config/sys-con/config_global.ini and change the value of use_dualshock_2nd_generation to true.
Bonus feature: You can now customize controller colors! Head over to sdmc:/config/sys-con/ and modify the color values for each type of controller. Most controllers already have customized colors in place.
