CemuShake

Linux and Windows app to simulate a shake motion input with a standard controller using the cemuhook protocol.

Anything that uses the cemuhook (dsu) protocol should be compatible with this, if it lets you map a standard controller alongside this.

The main purpose for the development for this tool was to do motion exclusive throws in Mario Odyssey with a standard Xbox controller (Ryujinx).

Usage

Configure your client (Ryujinx, Dolphin, etc...) like any other dsu client, with your ip and port 26760, or set up a custom port in the config file.
Turn on controller, open CemuShake and open your client. It should work.

By default RB (R1) is a shake with no gyro, to change this see the configuration section below.

Features

• AutoShake: Press select + start to active the auto shake. Lasts for about 4 seconds. Useful for mapping motion in yuzu/eden
• Gyro Compensation: Replays your motion back so that the simulated controller goes back to a consistent resting position after every press.

Configuration

You can configure the actions and some stuff creating a yaml config file in the same directory as the executable or in your home folder. It should be in $HOME/.config/CemuShake.yml

Valid configs are:

Key	Value	Description
port	uint	Network port to use for the server
gyro_compensation	bool	If feature is enabled
buttons	list	List of actions with its correspending button, see table below to see how to add an entry

Buttons list elements:

Key	Value	Description
id	uint	Controller button to map, see below for possible values
accX	float	Accelerometer value in X
accY	float	Accelerometer value in Y
accZ	float	Accelerometer value in Z
pitch	float	Value to apply to pitch over time
yaw	float	Value to apply to yaw over time
roll	float	Value to apply to roll over time

Buttons id values:

Id	Button (Xbox notation)	Button (PS notation)
0	A	X
1	B	O
2	X	□
3	Y	△
4	Back	Share
5	Guide	PS
6	Start	Options
7	LStick	L3
8	RStick	R3
9	LB	L1
10	RB	R1
11	Up	Up
13	Down	Down
12	Left	Left
14	Right	Right
15	Share	Mic (PS5)
16	Paddle 1 (Elite)	Not applicable
17	Paddle 2 (Elite)	Not applicable
18	Paddle 3 (Elite)	Not applicable
19	Paddle 4 (Elite)	Not applicable
20	Not applicable	Touchpad

Example config file (My setup for SMO)

---
gyro_compensation: true
port: 26760
buttons:
    - id: 7
      accX: 0
      accY: 200
      accZ: 0
      pitch: 30
      yaw: 0
      roll: 10
    - id: 8
      accX: 0
      accY: 200
      accZ: 0
      pitch: -30
      yaw: 0
      roll: 10

Building

You need SDL2 for the controller and yaml-cpp for the config, so install those through your package manager or with vcpkg as described in the dependencies section.

On linux you just need to run make
On Windows, install MSYS2, open the MINGW64 shell, install the dependencies below and run make

Dependencies

For ubuntu:
sudo apt-get install libsdl3-dev libyaml-cpp-dev

For Fedora:
sudo dnf install SDL3-devel yaml-cpp-devel

For Windows (MSYS2 MINGW64 shell):
pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-sdl3 mingw-w64-x86_64-yaml-cpp zip make
