PS5JustDance

Play Just Dance (2014 to 2022, PS4 versions running on PS5) on a jailbroken PS5 using Nintendo Switch Joy-Cons or any Smartphone, without needing Ubisoft servers, PSN, or a PlayStation Camera.

Built on the same freestanding stub injection architecture as PS5Instrumentalizer.

How It Works

All PS4 editions of Just Dance (Just Dance 2014 through Just Dance 2022) include native, 100% offline support for up to 4 PlayStation Move controllers (libSceMove.sprx), scoring dance moves purely from the 3-axis accelerometer and 3-axis gyroscope (no PlayStation Camera required).

PS5JustDance.elf runs in the background on the PS5:

Automatically detects any Just Dance edition (CUSA*) when launched.
Injects a freestanding, position-independent stub (build/stub.bin) into the game process and hooks both libSceMove (sceMoveInit, sceMoveOpen, sceMoveGetDeviceInfo, sceMoveReadStateLatest, sceMoveReadStateRecent, sceMoveSetLightSphere, sceMoveSetVibration) and libScePad (scePadReadState, scePadRead) for full in-game UI menu navigation.
Emulates up to 4 PlayStation Move controllers in real time from 3 simultaneous input sources:
- Switch Joy-Con via Python Bridge (tools/joycon_bridge.py): reads 1 to 4 Joy-Cons (Left or Right) over Bluetooth HID, converts IMU axes to the PS Move coordinate frame, maps the analog stick to D-Pad navigation, and streams 36-byte JDM1 UDP packets (port 9052).
- Switch Joy-Con or Smartphone via BetterJoy / DSU (Cemuhook): natively compatible with the DSUS/DSUC v1001 protocol (Windows/Linux/Android/iOS).
- Smartphone via Built-in Web UI (http://PS5_IP:8080): embedded HTTP server inside the PS5 payload featuring a bilingual (EN / PT-BR) mobile controller UI with live accelerometer readout, sensitivity control, dance simulation pad, and full D-Pad/PlayStation menu navigation buttons.

How to Use on PS5

Enable your PS5 jailbreak and etaHEN.
Send the payload to the console:
- Copy PS5JustDance.elf to /data/etaHEN/plugins/ and load it via etaHEN Toolbox, or
- Send it directly to the ELF loader:
```
nc -q0 PS5_IP 9021 < PS5JustDance.elf
```
Launch any Just Dance title (PS4 version running on PS5). An on-screen notification will confirm: "PS5JustDance: Joy-Con / Phone Move support active!".

Connecting Your Controllers

Option 1: Nintendo Switch Joy-Con with `joycon_bridge.py` (Windows / Linux / macOS)

Pair your Joy-Con(s) to your computer via Bluetooth.

Install hidapi and run the bridge pointing to your PS5 IP:

pip install hidapi
python3 tools/joycon_bridge.py --ps5-ip 192.168.1.100

On the Just Dance controller selection screen, choose PS Move and press ZR (Right Joy-Con) or ZL (Left Joy-Con) to join!

Joy-Con Button (Right / Left)	Emulated PS Move / Pad Button	Function in Just Dance
`ZR` / `ZL`	`T` Trigger + `Move`	Join lobby / Confirm PS Move
`R` / `L` / `Home` / `Capture`	`Move` Button	Action / Special
`Analog Stick`	`D-Pad Up / Down / Left / Right`	Navigate song list & UI menus
`A` / `Down`	`Cross (X)` + `Move`	Confirm in menus
`B` / `Left`	`Circle (O)`	Back in menus
`X` / `Up`	`Triangle`	Toggle option / Sort
`Y` / `Right`	`Square`	Favorite / Search
`+` / `-`	`START / OPTIONS`	Pause song

Option 2: Joy-Con or Smartphone via BetterJoy / DSU (Cemuhook)

On PC (BetterJoy / joycond-cemuhook): In /data/PS5JustDance/config.ini on the PS5, set dsu_server_ip = YOUR_PC_IP. The PS5 will automatically subscribe to port 26760 and map up to 4 Joy-Cons.
On Smartphone (MotionSource / DSUController): Point the app's UDP output to PS5_IP on port 9052.

Option 3: Smartphone via Built-in Web UI (`http://PS5_IP:8080`)

Open http://PS5_IP:8080 in your phone's browser.
Use the top-right PT-BR / EN button to switch the UI language at any time.
Select Player 1..4 and tap ENABLE SENSORS.
Unlocking Accelerometer over HTTP:
- Mobile browsers block DeviceMotionEvent on plain http:// origins by default.
- On Android (Chrome): Open chrome://flags/#unsafely-treat-insecure-origin-as-secure, add http://PS5_IP:8080, set it to Enabled, and relaunch Chrome.

Building and Testing

export PS5_PAYLOAD_SDK=/opt/ps5-payload-sdk   # or automatically uses ../.deps/sdk/ps5-payload-sdk
make        # builds build/stub.bin and PS5JustDance.elf
make test   # runs host unit tests (protocols, freestanding stub, and config/SFO parser)
make clean
