flydigi_ds4

Use your Flydigi Direwolf 2 (USB) as a DualShock 4 in jailbroken PS4 games.

A GoldHEN plugin that reads the controller over USB and hands its input to the game as if it came from a DS4. It works with the DS4 turned off, needs no adapter, and installs with FileZilla in a few minutes.

Why this exists

The PS4 only accepts controllers that identify as a DualShock 4 and pass Sony's cryptographic check. PC controllers (Flydigi, generic pads, 8BitDo…) speak "Xbox" and are simply ignored. The usual fix is buying an adapter.

This plugin takes another route: it runs inside the game, reads the controller straight from USB and gives the buttons to the game, which thinks it is talking to a DS4. Because the PS4 system never sees the controller, there is no auth check and no 8-minute timeout for unlicensed controllers.

Features

• ✅ All buttons, sticks and analog triggers
• ✅ Rumble
• ✅ Works with the DS4 turned off, or alongside it (both at once)
• ✅ Plug and unplug the cable while the game is running
• ✅ Settings file: button remapping (including combos), deadzones, triggers, rumble
• ✅ Per-game settings
• ✅ Touchpad: click, or swipe with the right stick
• 🧪 Gyro (experimental) for games with motion aiming or motion camera
• ✅ On-screen notifications (connected, disconnected, mistakes in the settings file)

Installation

You need FileZilla (or any FTP client) and GoldHEN with its FTP server on (port 2121).

1. Download flydigi_ds4-v1.3.zip from the Releases page and extract it.
2. In FileZilla, connect to the PS4's IP address, port 2121.
3. Upload flydigi_ds4.prx to /data/GoldHEN/plugins/
4. Upload flydigi_ds4.ini to /data/GoldHEN/
5. Add the plugin to /data/GoldHEN/plugins.ini:
   • Right-click plugins.ini → View/Edit
   • Under the [default] line, add:

     /data/GoldHEN/plugins/flydigi_ds4.prx
     

   • Save, close and confirm the upload. (If the file does not exist, upload the plugins.ini from the zip.)
6. In the GoldHEN menu, make sure Enable Plugins Loader is on.
7. Plug the Flydigi in with the USB cable and start a game. A few seconds later you will see "Flydigi connected".

To uninstall, delete the line from plugins.ini.

Default button map

Flydigi	PS4
A / B / X / Y	✕ / ○ / □ / △
LB / RB	L1 / R1
LT / RT	L2 / R2 (analog)
Menu (Start)	Options
View (Back)	Touchpad click
L3 / R3, sticks, d-pad	same
Flydigi/Home button	nothing (the PS button belongs to the system)

Settings

Everything lives in /data/GoldHEN/flydigi_ds4.ini, which you edit through FileZilla (right-click → View/Edit). Changes apply the next time you start a game. If something is wrong, an on-screen notification tells you the line.

Option	Values	Default	What it does
A, B, X, Y, LB, RB, LT, RT, START, BACK, GUIDE, L3, R3, UP, DOWN, LEFT, RIGHT	CROSS, CIRCLE, SQUARE, TRIANGLE, L1, R1, L2, R2, L3, R3, OPTIONS, TOUCHPAD, UP, DOWN, LEFT, RIGHT, NONE	table above	Remaps the button. Combos work too: LB = L1+R1
deadzone_left, deadzone_right	0 to 50 (%)	9	Stick deadzone
trigger_threshold	1 to 100 (%)	8	How far LT/RT must be pressed to count as pressed
vibration	0 to 100 (%)	100	Rumble strength
touchpad_mode	click or swipe	click	See Touchpad
gyro	yes / no	no	See Gyro
gyro_sensitivity	1 to 500 (%)	100	Gyro sensitivity
gyro_invert_horizontal, gyro_invert_vertical	yes / no	no	Inverts one gyro axis
notifications	yes / no	yes	Connected/disconnected notifications
log	yes / no	no	Writes /data/GoldHEN/flydigi_ds4.txt for troubleshooting

Per-game settings: add a section named after the game's ID and put only what changes in it:

[default]
vibration = 100

[CUSA17776]
vibration = 0
A = CIRCLE
B = CROSS

Touchpad

• touchpad_mode = click: View clicks the touchpad.
• touchpad_mode = swipe: while you hold View, the right stick becomes your finger on the touchpad, so you can swipe.
  • Quick tap on View: click
  • Hold View still for half a second: click and hold
  • R3 while holding View: click where the finger is
  • Release View and the right stick controls the camera again

Gyro (experimental)

With gyro = yes, the Direwolf 2's motion goes to the DS4 gyro, for games with motion aiming or motion camera.

Over USB the Direwolf 2 only reports horizontal and vertical motion, already processed. There is no tilt and no accelerometer, so games that use the controller as a steering wheel or a level will not work. Direction and scale were calibrated with motion tests but may vary between games: if the aim moves the wrong way, use gyro_invert_horizontal / gyro_invert_vertical, and tune the strength with gyro_sensitivity.

Limitations

• PS and Share buttons stay on the DS4: they belong to the system, not the game.
• The PS4 menus (outside games) still need the DS4 or the PS4 Second Screen app on your phone.
• One controller only: the plugin cannot add a player 2, because the PS4 only creates player 2 when another user signs in with a controller the system recognizes.
• Do not use it together with the gamepad_helper plugin (both patch the same part of the game).

Troubleshooting

The controller keeps connecting and disconnecting Replace the USB cable. A bad cable is exactly what caused this during testing.

"Flydigi connected" never shows up Check that Enable Plugins Loader is on, that the line is in plugins.ini, and that the controller was plugged in before or during the game. Set log = yes and look at /data/GoldHEN/flydigi_ds4.txt.

The game closes when it starts Delete the line from plugins.ini and open an issue with the game ID (CUSAxxxxx) and the log.

The controller keeps rumbling after closing the game Unplug the cable and plug it back in.

Controller not working?

Support can be added without me owning the controller:

1. In flydigi_ds4.ini, set log = yes
2. Plug the controller in and start a game
3. Download /data/GoldHEN/flydigi_ds4.txt and attach it to an issue

The log describes everything connected over USB, which is what I need to understand the controller.

Building (Windows)

powershell -ExecutionPolicy Bypass -File setup.ps1          # downloads the toolchain (~350 MB)
powershell -ExecutionPolicy Bypass -File tests\run_tests.ps1 # PC-side tests
powershell -ExecutionPolicy Bypass -File build.ps1           # builds out\flydigi_ds4.prx

Uses llvm-mingw, the OpenOrbis PS4 Toolchain and the GoldHEN Plugins SDK, at pinned versions downloaded by setup.ps1.

How it works inside

File	Role
source/main.c	Hooks scePadRead/scePadReadState (same technique as the official gamepad_helper plugin), merges the Flydigi into the DS4 data and forwards rumble
source/usb.c	Thread that finds the controller (any XInput FF/5D/01 interface), reads its reports through libSceUsbd and reconnects on its own
source/xinput.c	Xbox 360 USB report → neutral state (RawPad), including the Direwolf 2's motion bytes
source/translate.c	RawPad → DS4, applying the settings and the touchpad
source/gyro.c	Motion → DS4 gyro angular velocity
source/config.c	flydigi_ds4.ini parser
tests/tests.c	PC-side tests, including real reports and motion captured from a Direwolf 2

☕ Support the project

flydigi_ds4 is and will stay free and open source. It came from a simple frustration: a good controller I already owned that the PS4 refused to recognize. It took many hours of reverse engineering, console testing and tweaking to get here.

If the plugin saved you from buying an adapter, or just got you playing again with the controller you like, please consider a donation of any amount. It keeps the project alive, buys other controllers to test and gives me time to answer issues properly.
