PADEMU — DualShock 3 and 4 emulation
PADEMU lets a DualShock 3 or DualShock 4 stand in for a PS2 controller. The game sees an ordinary PS2 pad; PADEMU translates for it. Connect over USB or Bluetooth, on either pad port, with optional vibration and multitap emulation.
PADEMU is the work of belek666 — see Credits & Sources.
PADEMU is compiled in by default, so stock builds have it.
Setting it up
PADEMU is configured per game: Triangle on a title → Controller Emulation. The first row, Settings Mode, chooses between Global (follow the defaults set in Settings → Controller Settings → Controller Emulation) and Per Game (this title's own settings). See Per-game Settings.
| Option | What it does |
|---|---|
| Pad Emulator | The master on/off switch for this game. Everything below is greyed out while it is off. |
| Pad Emulator Mode | DualShock3/4 USB or DualShock3/4 BT (Bluetooth). |
| Emulation | Enable emulation on the selected pad port. Set this per port. |
| Vibration | Vibration for the selected port. Only available once that port's Emulation is on. |
| Multitap Emulation | Present a multitap to the game, for titles that support more than two players. |
| Multitap Emulator On Port | Which pad port the emulated multitap occupies. Only available with Multitap Emulation on. |
| Fake DS3 Workaround | A compatibility shim for counterfeit DualShock 3 units. Only shown in Bluetooth mode. |
The port rows are per-port: select the pad port first, then set Emulation and Vibration for it.
USB or Bluetooth
USB (ds34usb) is the simpler path — plug the controller into one of the console's USB
ports. Start here if you are not sure.
Bluetooth (ds34bt) needs a compatible USB Bluetooth adapter plugged into the console.
The controller is then paired to that adapter rather than to the console itself.
Fake DS3 controllers
Counterfeit DualShock 3 units are common, and many of them deviate from the real protocol enough to fail. Fake DS3 Workaround exists for those. It appears only when the mode is set to Bluetooth, so if you cannot find the option, check the mode first.
If a controller behaves erratically or will not connect at all, trying this toggle is cheap. It will not help a genuine DualShock 3, which does not need it.
DualSense (DualShock 5)
DS5 over USB is supported in the code and has been hardware-validated, but it is off in the default build. The entire DS5 path is compiled out, so a default build behaves identically to the build that is already hardware-proven.
-ds5.ELF downloads on the release. They are built best-effort: if that build fails for a given
run, the asset is skipped for that run rather than holding up the release, so it will not always be present.
See Releases.Troubleshooting
The PADEMU screen says it is not used with this core. The game's Loader Core is Neutrino. Change it to the OPL core, or accept that PADEMU is unavailable for that title.
The controller does nothing in game. Check three things in order: Pad Emulator is on; Emulation is on for the port you plugged into; and the Mode matches how you actually connected (USB vs BT).
No vibration. Vibration is per port and only becomes available once that port's Emulation is on. Confirm the port is right, then that vibration is enabled on it. This is separate from the menu's own Controller Vibration in Menus setting, which is about the RiptOPL browser rather than the game — see Controls.
A Bluetooth controller will not pair. Confirm the adapter is one PADEMU supports and is plugged into the console, then try Fake DS3 Workaround if the controller is not a genuine Sony unit.
Multitap options are greyed out. Multitap Emulator On Port only becomes available once Multitap Emulation itself is on.
