Have you tried installing the Extended Kernel? Performance won't be great, but Mypal should run under this, which I support. For best results, ensure your graphics drivers are up-to-date. Bad Ballsy Benchmark may not work on older graphics cards that don't support OpenGL stuff.

As far as the downloadable version is concerned, I don't support it on Windows 2000. By the sounds of this thread, you may be able to get Java 8 Update 121 running on 2000, which BBB should run under, but no promises.

Since I made my initial reply, there's been a new video created on installing Java 8 on Windows 2000. This doesn't require much messing around with system files. You may be interested.
