Turn your rooted Android phone into a Sony DualShock 3 controller. Pair a Bluetooth gamepad to relay its inputs, or use the on-screen controls directly — inputs are forwarded as authentic DS3 HID reports over USB to a PS3 or PC. Download the APK (arm64).
Important
Root access is required — ConfigFS and FunctionFS are kernel interfaces gated to root, and on Android the daemon needs to reclaim the UDC from the system USB stack before the gadget can bind.

droidshock3— Flutter Android app. Provides an on-screen DualShock 3 layout, Bluetooth gamepad pass-through with remappable inputs, and player LED feedback from the PS3's output reports.bridge— on-device TCP daemon. Owns the full gadget lifecycle: registers the DS3 USB device, binds it to the UDC, and streams HID reports in both directions between the app and the USB host.ffsds3— Dart library. Handles the low-level DualShock 3 USB emulation over FunctionFS, including input/output reports and EEPROM.
If you have a dev-board with a UDC port you can use the ffsds3 CLI directly.
Most boards require external power — the PS3 only supplies 100 mA before enumeration completes
(per the USB spec), which may not be enough to boot.
