How to Implement Virtual Gamepad Control in webMAN MOD via Web Browser

Developers can implement virtual gamepad control in webMAN MOD by sending HTTP GET requests to the /pad.ps3 endpoint, which triggers the V-PAD engine in include/feat/vpad.h to inject controller input via the cellPadLddDataInsert syscall.

webMAN MOD ships with a built-in virtual gamepad (V-PAD) feature that allows any web-enabled device to control a PS3 remotely. The implementation leverages the existing HTTP server to accept button commands through simple query strings, translating them into native controller inputs using the PS3 kernel's LD-D controller interface.

Understanding the Virtual Gamepad Architecture

The virtual gamepad system consists of two primary components: the HTTP request router that intercepts browser commands and the engine that translates those commands into hardware-level controller signals.

HTTP Request Routing in www_client.c

When the PS3 receives an HTTP request, the server implementation in www_client.c checks for the virtual gamepad endpoint. At line 563, the code sets a flag when the request path starts with /pad.ps3:

// www_client.c – line 563
bool is_pad = islike(param, "/pad.ps3");

This flag ensures the query string is forwarded to the pad engine rather than processed as a standard file request. The router handles all incoming connections from smartphones, tablets, PCs, or automation scripts uniformly.

Core Engine Implementation in vpad.h

All virtual pad logic resides in include/feat/vpad.h. This header defines the HTTP API and manages a fake controller registered with the PS3 kernel as an LD-D controller.

The engine performs three critical functions:

• Registration: The register_ldd_controller() function creates a virtual controller instance, while unregister_ldd_controller() removes it when sending /pad.ps3?off.
• Command Parsing: The parse_pad_command() function interprets query strings for button presses, analog stick movements, hold/release states, and special actions like swapping X/O buttons.
• Data Injection: The engine builds a CellPadData structure and injects it into the system via the cellPadLddDataInsert syscall.

After each command execution, the default pad state is automatically restored to prevent interference with normal gameplay.

Virtual Gamepad HTTP API Reference

The virtual gamepad accepts commands through URL query strings. The base endpoint is http://<ps3-ip>/pad.ps3 followed by these parameters:

• /pad.ps3?off – Unregisters and disables the virtual controller.
• /pad.ps3?cross|square|up – Presses X, □, and UP sequentially with auto-handled delays.
• /pad.ps3?analogL_up|hold – Moves the left analog stick up and maintains the position.
• /pad.ps3?cross=enter – Maps the X button to act as the Enter button (requires PS3 reboot).
• /pad.ps3?circle=swap – Swaps the functions of O and X buttons (requires PS3 reboot).

Multiple actions can be chained using the pipe (|) delimiter for complex inputs.

Implementation Walkthrough for Developers

Integrating virtual gamepad functionality requires understanding the compile-time configuration and the execution flow from HTTP request to hardware injection.

Enabling the VIRTUAL_PAD Macro

The entire virtual gamepad implementation is guarded by the VIRTUAL_PAD compile-time macro. Developers must ensure this flag is defined during the build process to include the pad engine in the binary. Without this macro, the /pad.ps3 endpoint returns a 404 error.

Execution Flow and System Integration

When a browser sends a request to http://<ps3-ip>/pad.ps3?cross, the following sequence occurs:

1. www_client.c detects the /pad.ps3 prefix and sets is_pad = true.
2. The dispatcher in cmd/pad_combo_play.h invokes parse_pad_command().
3. The parser ensures the virtual controller is registered via register_ldd_controller().
4. The command is translated into a CellPadData structure.
5. cellPadLddDataInsert injects the data into the PS3 kernel.
6. The system optionally sleeps for hold states, then clears the input.

This flow executes within milliseconds, providing near-real-time responsiveness for remote control scenarios.

Code Examples for Browser and Automation

Developers can trigger virtual gamepad inputs from any HTTP client. Below are implementation examples in shell, Python, and JavaScript.

Send a button combo from a shell script using curl:

# Press Cross, Square, and Start in sequence

curl "http://192.168.1.42/pad.ps3?cross|square|start"

# Hold the left analog stick up for 2 seconds

curl "http://192.168.1.42/pad.ps3?analogL_up|hold"

# Swap X/O button mapping (requires PS3 reboot)

curl "http://192.168.1.42/pad.ps3?circle=swap"

Control the PS3 programmatically using Python:

import requests
import time

base = "http://192.168.1.42"

# Press L1 then release

requests.get(f"{base}/pad.ps3?L1")
time.sleep(0.1)
requests.get(f"{base}/pad.ps3?release")

Implement browser-based controls using JavaScript:

function sendPadCommand(cmd) {
  fetch(`http://192.168.1.42/pad.ps3?${cmd}`)
    .then(r => console.log('sent', cmd));
}

// Map a UI button to Triangle + R2 combo
document.getElementById('myBtn')
        .addEventListener('click', () => sendPadCommand('triangle|R2'));

Advanced Integration with Combo Commands

For complex automation, webMAN MOD supports the /combo.ps3 endpoint defined in include/cmd/pad_combo_play.h. This allows developers to chain multiple pad commands into a single HTTP request, reducing network overhead for scripted sequences.

The combo handler processes the same query syntax as /pad.ps3 but executes actions with precise timing intervals. This is particularly useful for automation tools, remote-play overlays, or testing frameworks that require deterministic input sequences.

Summary

• webMAN MOD provides a complete virtual gamepad solution accessible via HTTP requests to /pad.ps3.
• The system uses include/feat/vpad.h to register an LD-D controller and inject inputs via cellPadLddDataInsert.
• HTTP routing is handled in www_client.c at line 563, which detects the pad endpoint and forwards commands.
• Developers must compile with the VIRTUAL_PAD macro to enable the feature.
• Simple query strings control buttons, analog sticks, and system settings, while /combo.ps3 supports complex input sequences.
• Any device capable of sending HTTP requests—including smartphones, tablets, and automation scripts—can control the PS3 remotely.

Frequently Asked Questions

What is the V-PAD feature in webMAN MOD?

The V-PAD (Virtual Gamepad) is a software-based controller implementation that allows remote control of a PS3 through HTTP requests. It registers as an LD-D controller with the PS3 kernel and translates web-based commands into native controller inputs using the cellPadLddDataInsert syscall, enabling any web-enabled device to function as a gamepad.

How do I enable virtual gamepad support when compiling webMAN MOD?

Virtual gamepad support is controlled by the VIRTUAL_PAD compile-time macro. Developers must define this flag during the build process to include the pad engine code from include/feat/vpad.h in the final binary. Without this macro, the /pad.ps3 endpoint is unavailable and returns a standard HTTP 404 response.

Can I use the virtual gamepad from any device with a browser?

Yes. Any device capable of sending HTTP GET requests—including smartphones, tablets, PCs, or IoT devices—can control the virtual gamepad. The interface accepts standard HTTP requests to http://<ps3-ip>/pad.ps3, making it compatible with browsers, command-line tools like curl, Python requests, or JavaScript fetch APIs without requiring specialized drivers or apps.

What is the difference between /pad.ps3 and /combo.ps3?

The /pad.ps3 endpoint processes individual button presses and immediate actions, restoring the default state after each command. The /combo.ps3 endpoint, handled by include/cmd/pad_combo_play.h, is optimized for chaining multiple commands with specific timing intervals, making it ideal for automation scripts that require complex input sequences like cheat codes or automated navigation menus.
