As i can see, version 1.51 of SNES9X has that Netplay function which was left out in some earlier versions, probably due to programming problems. But now it is back and i want to ask how well this feature works with different internet connection, because it would be really nice to play DKC together just for fun

If this works well on the emulator side, the only problem left is the timezone you live in. Or just set the alarm clock for 3 o'clock in the morning and have fun with people around the world!
Oh well, we have to decide what version will be used for this purpose. (U) or (E)? 1.0?
