VitaOxiPad

Turn your PS Vita into a gamepad for your PC!

Based on VitaPad by Rinnegatamante and Rust-based VitaPad by saidsay-so.

VitaOxiPad

Description

VitaOxiPad is a client-server application that turns your PS Vita into (almost) a DualShock 4. The PS Vita acts as a server to which the PC client will be connected within the local network (WiFi).

The server part is written in C++, the client part is written in Rust.

What works

Feature	Support	Details
Buttons	✅	-
Sticks	✅	-
L1 and R1	✅	Press only, as the PS Vita does not have analog triggers. This emulates a full press
L2/R2 and L3/R3 emulation	✅	Can be used of the back or front PS Vita digitizer for it
Select and Start	✅	-
Accelerometer and gyroscope	✅	A little less accurate than the DualShock 4, but still usable
DualShock 4 digitizer emulation	✅	Emulates up to two-finger simultaneous input, same as DualShock 4
Any configuration	✅	You can choose from ready-made configurations
DS4Windows support	✅	You need to enable Moonlight support[*]
Sound	❌	Probably will never be realized

[*] - Moonlight support can be found in the schmaldeo DS4Windows fork. This option can be found in Settings -> Device Options -> Virtual Controller Support.

Uses and options

$ VitaOxiPad-x64.exe --help
Usage: VitaOxiPad-x64.exe <ip> [-p <port>] [-c <config>] [--polling-interval <polling-interval>] [-d]

Create a virtual controller and fetch its data from a Vita over the network.

Positional Arguments:
  ip                IP address of the Vita to connect to

Options:
  -p, --port        port to connect to (default: 5000)
  -c, --config      buttons and touchpads config (default: standart)
  --polling-interval
                    polling interval in microseconds (minimum = 4000)
  -d, --debug       enable debug mode
  -v, --version     show version information
  --help            display usage information

Configurations

There are currently 4 DualShock 4 configurations emulations that can be selected at client startup:

Configurations name	PS Vita L1\R1	PS Vita front digitizer	PS Vita rear digitizer
`standart`	L1\R1	L3\R3	L2\R2
`alt_triggers`	L2\R2	L3\R3	L1\R1
`rear_touchpad`	L1\R1	upper area - L2\R2, lower area - L3\R3	DualShock 4 digitizer
`front_touchpad`	L1\R1	DualShock 4 digitizer	upper area - L2\R2, lower area - L3\R3

To better understand the emulation behavior, you can run 3D Controller Overlay after connecting your PS Vita.

Bugs

Rarely, a server on PS Vita can crash with an error. The causes are being investigated. Happened to me more than once in 3-4 hours of play;
Sometimes, the imput-lag increases a lot. This may be due to a bad WiFi connection.

Installation

The server has to be installed on the PS Vita and the client on the PC.

Requirements for Windows

ViGEmBus

Client compilation

Windows

To compile on Windows you will need

Make and Cmake;
Flatbuffers (flatc);
Rust (cargo).

You can use MSYS2, which provides this in a convenient way.

Dependencies you will need for MSYS2 MINGW64:

pacman -S mingw-w64-x86_64-rust mingw-w64-x86_64-flatbuffers make git wget cmake

Clone the repository and log into it:

git clone --recurse-submodules https://github.com/DvaMishkiLapa/VitaOxiPad.git
cd ./VitaOxiPad

Build the client side:

cd ./client
cargo build --release --bin cli

You can check the finished binary by running in it:

 ./target/release/cli.exe your_PS_Vita_IP

PS Vita server compilation

Make sure that you have cmake installed;
Make sure you have VitaSDK installed and configured (try vdpm);

Sometimes, for whatever reason, flatbuffers are not installed in the VitaSDK (fatal error: flatbuffers/flatbuffers.h: No such file or directory).

You can install it manually via vdpm. Do this after installing the VitaSDK via vdpm:

./vdpm flatbuffers

Install flatc for your system. For Linux:

git clone https://github.com/google/flatbuffers.git && cd flatbuffers
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Release
make -j
./flattests # this is quick, and should print "ALL TESTS PASSED"
sudo make install
sudo ldconfig
flatc --version

Build the project with the following commands:

cmake -S server -B build
cmake --build build

Then, install the generated VitaOxiPad.vpk file on your PS Vita.

Why Oxi?

Now there are many projects with the name VitaPad. It's very confusing.

Oxi - oxidation, the process that causes rusting.
