First, you need Quake 3 already installed. Note that the installation of Team Arena will update your existing Quake 3 install to v1.27.
Now, I believe the rip is from Fantasy group judging from the size.
This is from that nfo:
1. Unzip.
2. Run install.exe or unace manually into EXISTING Q3 directory.
3. Run setup.bat (you may delete the folder /missionpack/sound/ after)
4. Run regsetup.exe
5. Play the game with quake3arena.bat
6. CD-KEY: TSBH-7CCG-DPWP-B2LT-84.
The texture fix is for a different smaller rip from Visper group.
There is supposed to be a fix for the Fantasy rip also...if it wasn't included then it might not work?
Scaryfun.
