Hi Tobias,

Thank you for your timely reply.

(As a side note, can you please CC the messages to me, because I am not subscribed to the guix-patches mailing list. Maybe I am using debbugs in some 
wrong way).

That's a good point. I changed the description to something more appropriate.

Oops, I didn't mean to say that it's tied to the Linux kernel (although I don't think it's developed/tested on other platforms). I just wanted to 
contrast that with the old original Osu! game which is for Windows.

 > Could we package these separately?  How are they licenced?

I am not sure. You basically have to download them manually from the Osu! website or from other places on the web.
I don't think they are licensed very well at all..

Yeah I am not sure about the headers, but the COPYING file indicates that it's GPL 3

Best,
Dan
