Hello there guys thanks a lot for all your work.

I am trying to build the repo using latest packages and just find, since commit 1bb5a21 of Libnx on the file libnx/nx/include/switch/runtime/devices/socket.h the structure definition SocketInitConfig removed the element bsdsockets_version hence on the file MAIN.CPP of ShareNX-Overlay you must remove (or comment) the line 31 (32 after this PR):

//    .bsdsockets_version = 1,

please add this to the present PR.

Hi mate, is there any chance this could be merged?

I'll try this later today and build a release.
