I was able to successfully install Heretic II 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
Note that it is necessary to avoid using the h2_setup.exe launcher file in the root directory of the CD-ROM since it hangs. Use the setup.exe file in the \setup directory instead.
The Version 1.6 Enhancement Pack (ht2_ep_v1-06.exe) also installed successfully.
The game plays well using the software renderer, but selection of the OpenGL renderer forces a return to the console.
Cutscenes, sound, and graphics seem to be correct. Menus display correctly. There is no in-level music.
I have not tested multiplayer/network play.
