I'm now hosting a dedicated server for the PC version of KISS: Psycho Circus: The Nightmare Child in case anyone wants to try out the online multiplayer. Unfortunately online mode was dropped from the Dreamcast version so this is the only way you can experience it. The server details are below. You might have a problem seeing the server with Windows 7 and up. I got it to show up once on Windows 10 but haven't been able to see it since. It seems completely random. I've tried troubleshooting the issue but I can't figure out what the problem is. Anyway, if you have an XP (or earlier) machine, you should be able to see the server and join without any issues.
