I noticed this by accident like a month ago when testing a GMA 950 for stability, I needed something so thought about an old 3dmark, I normally use files from my old hard drives but was to lazy for that and was pleased with this, all the keys there, so I could finally change settings in some of them, also 06 (maybe also 05) originally would not show your score without a key (unless you uploaded to their site)
but it's nice of them to keep them all available and unlocked with the key, a shame they deleted the old results database like 5 years ago, I had my results from all my PCs as old as April 2000 there.
