Yes splitcam support has been decidely vague.
I don't know which if any versions run on 98 however I dont think it was originally released
with 98 support but may have been subsequently upgraded,I have a few earlier versions you can play with,I gave up the testing at the nag4reboot stage after installing the required .dll.
If you get a result make sure you update your post on the splitcamera forum.
