How do I run Supercade?

OK I know this is an odd question but I tried to start a session in Supercade but the game window didn’t come up. I do get a small blue square with an S in it in the bottom right panels but the game itself doesn’t run.
Do I need to upgrade my .NET Frame software? I’m sure it’s the latest ver. since Vista updated it a few days ago.

You need to wait for someone to connect, Tizoc i suggest using GGPO

I can’t seem to run Supercade from Firefox either, because one module isn’t updated (FFClikOnce) along with firefox (not that it’s really needed, but…).

I’m playing 3rd strike myself and I was told GGPO runs the poorer network code compared with Supercade. Has anything changed on this front ?
