Dolphin, the GameCube and Wii emulator - Forums

With the addition of Golf Mode, playing singleplayer games with a friend over Netplay is now a possibility... or it would be if both players could control port 1.

The solution could be either one of these:
a. Allow both players to have control of one port at all times
b. Allow players to switch ports while the game is still open

I don't know a lot about programming but I imagine implementing one of these options wouldn't be too hard.

I hope I get an answer because I would love to be able to do this.

Actually what you're asking for is tremendously hard compared to golf mode, which is why it hasn't been done.
