I spent some time setting up a Pentium II with Windows 98 and a Voodoo 3 on PCem this weekend.
It's really cool software, and a fun little project.
I spent a little time playing some Rainbow 6 (crazy how much the genre has changed over time) and Castle of the Winds 2.
Black and White runs well, but has some pretty bad audio stutter that I'll have to figure out a solution for.
Do you have a favorite game from the period that I should try? I'm particularly interested in ones that are hard to run on modern versions of Windows.
Deus Ex runs way better natively than in PCem
