This crack is for the Diamond Multimedia (S3) version of Quake III Arena, which is designed to run on S3 Savage4 and Savage2000 series based cards with texture compression enabled. This version can be found at http://www.dmmunderground.com/ along with maps that use this feature.

Cracked by Zuofu (they didn't try very hard on the CD-check)

Thanks go out to PeeGee for his excellent patch engine (Ultra Patcher 32)!
