[MassEffectMouseFix] Remove Mouse Acceleration

Overview

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.

Overview

While the mouse controls are pretty responsive, the first Mass Effect suffers from mouse acceleration, which can’t 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.

• 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

Important: This fix relies on the latest, fully patched executables of the supported versions. Older versions or ones that otherwise have been tempered with won’t work. This also means that if a game were to be patched — which is very unlikely at this point — it would break the fix and require it to be updated.

• Steam
• Origin
• Retail, v1.02

Note: All available versions of the game can be enabled on Origin one way or another. See this link[pcgamingwiki.com] for details.

Note: The fix does not make any permanent changes to the game or the system and can easily be removed (see below).

1. Download this[community.pcgamingwiki.com] zip-file
2. Extract the file dinput8.dll to your main game folder. For example: “C:Program Files (x86)SteamsteamappscommonMass EffectBinaries”.
3. Start the game like you would normally, for example directly through Steam or Origin

1. Remove or rename the dinput8.dll from the folder of the game.

Known Issues

There are currently no known issues with the mod.

Additional Information

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.

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.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.

Version History

• The y-axis inversion setting now works as intended
• Updated address system to increase compatibility with modified versions of the game

• The camera will no longer move when the player is in a menu
• The fix will now respect the inversion setting of the y-axis

• Fixed bug that caused the Steam and retail version to crash on start

• The fix should now correctly work with Origin versions from any region

• The DLL can now also be renamed and used as xinput1_3.dll. This is to make the fix compatible with other fixes/mods that also use a dinput8.dll for loading (This is can now be achieved via remote loading. See Loading Other Fixes/Mods/Injectors for details)

• Patching a supported version to be large address aware no longer prevents it from being detected correctly. This is to ensure that the fix works with certain mods

• Added support for retail version of the game
