So when you release it you have to make it open-source <.<.
What about current progress for 3DS client?
That's not what he meant to say.
It will definitely be open-source. The fact is that we are waiting to have something working before releasing everything, alongside the sources.
The 3DS client is on its way. Like I said, just a lot of code. I would say 20%, but that's surely not accurate since we are thinking about new functionalities everyday.
The code will be readable soon, hopefully ^^

Since that's almost only lpp.
