I was able to successfully install Tribes 2 (Sierra Best Seller Series version, Build 25034) in a Win98 bottle on the following machine:
Soyo SY-7ISA+ Intel i815 Motherboard
Intel Pentium III 866 MHz Processor
512 MB SDRAM
PNY Verto GeForce FX 5200 AGP 8x 256 MB DDR
Creative Labs Sound Blaster Live! 5.1 PCI Sound Card (SB0220)
Samsung CD-RW/DVD Drive Model: TS-H492A/RSWN
Dual Boot openSUSE Linux 10.3/Windows XP Pro SP3
CodeWeavers CrossOver Games for Linux Version 7.1.2
In order to start the game, it is necessary to execute the autorun.exe file in the root directory rather than another .exe file elsewhere.
There are graphical anomalies in the training missions. I can't see waypoints on the HUD, and rendering of surfaces in the distance isn't correct for example. The OpenGL renderer is apparently the only option.
Sound effects, voices, and menus seem to work fine.
I have not tested multiplayer/network play.
