Ctroller-android is a program that lets you use your 3DS as an input device for your Android system via the uinput kernel module.

It consists of a client that runs on your 3DS, continously streaming the 3DS input data to a server on your Android device. The server exposes a virtual device to your system, interpretes the data it receives and writes it to a event node under /dev/input/event* or similar. The kernel gamepad input documentation can be found here.

This is a port of phijor's ctroller application to Android.

Note: To use this your phone must be rooted with a uinput enabled kernel. ARM(64) only.

Installation

Prerequisites

ctroller-3ds, you can use the pre-built binaries by phijor (3DSX or CIA).

ctroller-android, you can use either the ELF binary, or the Android app.

To run the server, the uinput kernel module needs to be loaded: 

$ modprobe uinput

Installing

Create a directory ctroller in the root of your SD card.

Place ctroller.cfg in there and replace the IP with the one of your PC (the config file should now be at sdmc:/ctroller/ctroller.cfg).

Install ctroller-3DS using either one of the following:

  • CIA - Install .cia with the CIA-manager of your choice.
  • 3DSX - Copy .3dsx and .smdh to /3ds/ctroller/ on your SD card.

Install ctroller-android using either one of the following:

  • APK - With a simple UI.
  • ARM64 - Run ELF binary manually.

User guide

App version

Run the application and press start.

Launch the ctroller.3dsx or ctroller.cia application on your 3DS using a homebrew launcher of your choice.

ELF binary

Start the ELF binary manually by copying to a executable location (like /data/local/tmp/) and running: 

$ ./ctroller

Flags if you manually run the binary: 

 -d  --daemonize              execute in background
 -h  --help                   print this help text
 -p  --port=<num>             listen on port 'num' (defaults to 15708)
 -u  --uinput-device=<path>   uinput character device (defaults to /dev/uinput)
 -k  --keymap                 use a keymap file (if not set, ctroller will use the default keymap)

Then launch the ctroller.3dsx or ctroller.cia application on your 3DS using a homebrew launcher of your choice.

For development purposes, the 3DS-Makefile includes a run target that uses 3dslink to upload and run the application using the Homebrew Menu NetLoader.

Custom keymap file

To remap the buttons in a way you want, you need to create a file with a button label on each line. The default mapping is this: 

A
B
X
Y
START
SELECT
L
R
ZL
ZR

To modify it, copy the above into a file, and swap keys around. The order is very important; any key in your custom keymap will override the default one on the same line.

To use this keymap with ctroller-android, use the -k option (see above).

For example, to change the layout to be more like an xbox, you can swap A and B; X and Y; R and ZR; and L and ZL. The keymap file will look like this: 

B
A
Y
X
START
SELECT
ZL
ZR
L
R

Notes

This program is intended to be used in a private network.

For simplicity, the server right now accepts any connection on it's port, which might pose a security risk if others can send data to it.

This will be changed in future releases. For now, you probably shouldn't be using this in a public network.
