Is PvP Online Play Possible?

One of my favorite past times from college was when my friends and I would get together and play gamecube. We usually would play Mario Golf: Toadstool Tour, Double Dash, or Super Strikers. Since we all graduated and moved away from each other, we have been looking for a way to still play together online.

I cant imagine that isn't possible, but so far I haven't been able to find any way to do it. Any help would be appreciated. Thanks
