I got it running on w98se, havn't got nvidia card tho.
Here's what i've done, i did not invented this, i got info from other posts in fileforums and constructed this 'manual' lol.
U can do it other ways but let me just tell u how mine install did go.
1. Burn Disc's with CloneCD 4.3.1.9 'Protected Game' mode. (or higher version)
2. Installed game from cdr's, remove the disc's from cd-roms.
3. Used the latest Deamon tools 3.46 to mount cd1

4. put Deamon tools 'Emulation' to SafeDisc & after that the deamon tools icon should be green next to your clock in the taskbar.
5. Uninstall CloneCD, now if u have the newest clone cd uninstall will not be needed so i've read, but if u got the mesage 'Cd/DVD emulation software detected' thing u must uninstall clone CD. (or other out of date emulation software)
6. Run the game & enjoy (i didnt enjoy btw

)
Other way is (that i didn't do) without burning is to mount all discs CCD files, install the game & unintall all out of date emulation software. (even registration info, like with CloneCd uninstall, just to make sure)
So i'm not claiming this is the best way, but the way it works on my w98se machine.
