The Despecialized Editions of the original Star Wars movies are a de-mix of the DVD releases, restoring them to the color, edits and pacing of the original cinematic releases.
Search for "despecialized" on your favorite torrent tracker (I found mine on The Pirate Bay, which was a nearly nostalgic experience!). The colors, especially, are not to be missed.
This is a reconstruction of the 1977 theatrical version of STAR WARS. The original shots were painstakingly restored using various sources (listed below) and the film received an extensive shot by shot colour correction based on a fade free 1977 I.B. Technicolor Print.
The remastered (v2.0) version represents a significant improvement in picture quality over the earlier version.
Version v2.1 further improves upon the previous version mainly by refining the color correction but also by replacing many of the despecialized shots with higher quality ones.
Version v2.5 offers few more little tweaks to the picture and contains an unprecedented number of audio options, including lossless DTS-HD tracks for the original mixes, an isolated score, four different commentary tracks and dubbing tracks in ten different languages and dialects.
