Is it possible to use Hamachi for Mario Kart Double Dash BBA LAN?

[Kokonoe]

I've messed around with a few settings and can't seem to figure out how to play Mario Kart Double Dash via Broadband Adapter LAN in Hamachi.

Finally i could find a thread about this without making a new one

When it comes to BBA + Dolphin + Hamachi (GC - Mario Kart DD) its hard to find any infos.
I've messed around with OpenVPN, Xlink and Hamachi. No Success yet.
It cannot find the other GameCube (Dolphin)

Is that even possible?
Can someone please give some tips ?

Me and a friend want to play over the Internet, without Netplay.
With Netplay (Single-Core) it runs to slow for us.

In this last video it runs on 1 PC, so it should be possible to make it over hamachi too ?

(btw: Ports unlocked, Firewall off)
Ping a Friend over Hamachi works fine too.
