Tutorials/Update LWJGL (Legacy)

What is LWJGL?
LWJGL is the LightWeight Java Game Library. Essentially, it is what Minecraft uses for graphics, sound, and input.

Why update?

 * Minecraft will not ship with the latest version of LWJGL.
 * Updating will fix some input bugs where keys seem to get stuck if you click at the same time. It also removes the "ghost" mouse pointer clicking.
 * Some users report a performance increase upon updating.
 * This can also potentially fix some issues regarding sound not working/cutting out.
 * It has also been reported to fix intermittent crashes on Windows.

Where to download
http://lwjgl.org/download.php

Select the latest stable release and download the lwjgl-X.X.X.zip.

Note: some people reported that release 2.8.2 causes a bug in which you cannot exit the options screen; this appears to be fixed in 2.8.3 (released 1/23/2012).

Note: On MOST 64 bit computers, the lwjgl64.dll update will cause a black screen crash (as of stable release 2.8.1). Backup that file before updating it so you can rollback if there is a problem with it. Better yet, backup all files before updating. Stable Release 2.8.3 appears to fix the black screen issue

Note: Again on several 64 bit computers, the OpenAL64.dll update can cause a sound glitch that makes bursting sounds. Keep a backup in case you need to rollback.

What to replace
In the lwjgl-X.X.X.zip, there should be two folders, named jar and natives. You should replace the files in .minecraft/bin and .minecraft/bin/natives with the versions from the .zip.

You should replace these files:

In .minecraft/bin/ (All operating systems)
 * jinput.jar
 * lwjgl.jar
 * lwjgl_util.jar

In .minecraft/bin/natives/ (GNU/Linux)
 * libjinput-linux.so
 * libjinput-linux64.so
 * liblwjgl.so
 * liblwjgl64.so
 * libopenal.so
 * libopenal64.so

In .minecraft/bin/natives/ (Windows)
 * jinput-dx8.dll
 * jinput-dx8_64.dll
 * jinput-raw.dll
 * jinput-raw_64.dll
 * lwjgl.dll
 * lwjgl64.dll
 * OpenAL32.dll
 * OpenAL64.dll

The .minecraft folder's location varies by operating system.
 * Windows: %appdata%/.minecraft
 * Mac OS X: ~/Library/Application Support/minecraft
 * GNU/Linux: ~/.minecraft
