Adaptive Triggers for RE4 Remake

Description

DSZ is a lightweight DLL that replaces DSX/DSY middleware. It drives DualSense adaptive triggers directly via HID — no background services, no extra dependencies. It initializes automatically when the game loads.

I was too focused on making the Lua script communicate directly with the DLL, so I didn't polish many aspects – for example, handling situations where you can't fire, trigger release on fire interval, burst fire, etc. If you have any improvements in mind, feel free to leave a comment.

What I did manage to finish are the zero‑deadzone and SMG recoil settings – these two are at least better than what’s already available in the community. Some weapons were left out due to time constraints. The rifle frequency seems to be around 9 Hz – you can figure that out yourselves 😢.

I've also provided a test tool – place it in the same directory as the DLL, initialise the DLL, and you can test all the effect modes. Bear in mind that some modes might have been removed in newer Sony firmware, and parameters outside the specified ranges can also cause the effect to fail.

Forgive me – I should have brought in Claude earlier to help me understand Deepseek; DS kept going in circles and ended up costing me a lot of money.

Updated version

Installation instructions

Lay out any steps users must follow to install your mod

1. Install REFramework .

2. Copy and Paste.

Port 6969 must be free — close DSX/DSY or any other application that might be using it.

Main features

• []Direct HID adaptive trigger control — supports 10 native HID modes (official + unofficial + legacy).[/]

  []USB + Bluetooth dual‑mode — automatically detects connection type and works with both. Note: RE4R do not natively support Bluetooth input for the DualSense, but this mod can still control the triggers over Bluetooth as long as the controller is paired and connected.[/]

  []Multi‑controller support — all connected DualSense controllers receive the same effects simultaneously.[/]

  []Does not interfere with game vibration — only trigger flag bytes are updated; rumble, LED, and mic bits remain untouched.[/]

  []Zero dependencies — hidapi is statically linked; no external files required.[/]

  []Lazy reconnection — automatically re‑establishes the HID handle if the controller is disconnected and reconnected.[/]
