[BUG] minecraft opens on black screen

[MeLlamoGamer]

Hello, I have a problem, when trying to start any version of Minecraft it appears black with some errors on the console.
I am trying to use this launcher because from what I have seen it is the only reliable launcher to use on such an old operating system.

My OS:

• OS: Windows 2000
• Launcher version: 1.09_16 Universal JAR
• Processor architecture: x86
• Graphics driver: Mobile Intel(R) 945 Express Chipset Family
• Java 6

Here are the logs:

You need to manually download version jars for some versions, as Java 6 can't download them. Read README.md

You also need to download LWJGL that supports Java 6. I believe this should do the job: http://files.betacraft.uk/launcher/v2/assets/libraries/lwjgl/lwjgl-2.9.4-nightly-20150209-java5.jar

Replace your current lwjgl.jar in .betacraft/bin/ for this file. Make sure it has the same name as before (lwjgl.jar).
