Mass Effect Mouse Fix

Download Sources


TL;DR

This fix makes Mass Effect use raw mouse input and removes the game’s mouse acceleration. It is easy to install and use and does not require any external configuration.

Quick start guide:

  1. Extract the file dinput8.dll to your main game folder. For example: "C:\Program Files (x86)\Steam\steamapps\common\Mass Effect\Binaries\"
  2. Start the game like you would normally, for example directly through Steam or Origin

Features

While the mouse controls are pretty responsive, the first Mass Effect suffers from mouse acceleration, which cannot be turned off via the ingame settings or with the usual approaches for other Unreal Engine 3 games. This fix removes the acceleration by acquiring raw mouse input and injecting it directly into the game’s input function.

Its features include:

  • Raw mouse input
  • No additional smoothing or positive/negative mouse acceleration
  • Configuration via the ingame settings as usual
  • Simple installation and usage without any external configuration

Instructions

Install

The mod does not make any permanent changes to the game or to Windows and can easily be removed.

  1. Extract the file dinput8.dll to your main game folder. For example: "C:\Program Files (x86)\Steam\steamapps\common\Mass Effect\Binaries\"
  2. Start the game like you would normally, for example directly through Steam or Origin

Uninstall

Additional Information

Antivirus Software

Since this mod consists of an executable DLL file that uses “hacking techniques” such as injection and hooking, it could be classified as malicious by antivirus software. In that case, it might be necessary to add an exception rule to the scanner.

If you lack the trust in random people on the internet — and I would not blame you — feel free to use a meta online virus scanner like VirusTotal to verify the file.

Loading Other Fixes/Mods/Injectors

To increase the compatibility with other mods or injectors that are using a wrapper DLL, this fix offers two methods for remote loading of additional files. Note that there might still be compatibility issues between the different fixes, mods or injectors that have nothing to do with the loading process.

File method:

The mod will load another dinput8.dll automatically if it has the name dinput8_Remote.dll. Just rename the DLL you want to load accordingly. Using this method will lead to an error if the renamed DLL is not itself a dinput8.dll.

Folder method:

The mod will also automatically load all DLLs regardless of their names in a dinput8_Remote sub-directory. Just create a corresponding folder in the install directory of the mod. This is the only way to load multiple (conflicting) files.

    1. I am not sure if that is necessary, since there already is a way to disable the mouse acceleration in that game through manipulation of a config file. It is a little fiddly, but I doubt that that there is enough demand for a separate fix.
