You must use a Development Version of Dolphin 4.0-5234 or greater or this
pack will not work! Just use the latest Development Version!

The pack has lag spike issues on some development builds. This was fixed in
Dolphin 4.0-5716, so use this revision or newer!
It is required that you delete previous texture pack versions before
installing new ones to prevent texture conflicts!
Pre-Release Version: 6.1b (March 8, 2015)
Contains only DDS textures. This version is a sort of "pre-release" to an
upcoming v6.2 release that should for now help with lag/stuttering.
