Started months ago, found it in my file system today and decided to finish it up.....I present you my own implementation of the gCn client.....in python!
Currently the configuration sucks, you litterly have to edit the script (lines 5-8 )
And I have no idea how to check the calc id, so you'll manually have to put it in there, as of now, too (line 86).
Please note that it is, to me, also pretty old code and I still need to re-do quite some to get a more solid internal structure.
Also, here's the code: http://pastebin.com/dn7yfrwR

We're working on all of these shortcomings at the moment on IRC. Sorunome, if you find that I'm not answering IRC questions (I sometimes miss them), then feel free to post specific questions here.

Kerm, is it normal for yours that it misses every now and then a line sent from the calculator, as mine seems to do that (i still manage to establish the connection again but I am never able to fetch the data sent)

EDIT: This time the config is way more easy, you only have to edit all the top of the file.

it seems to work pretty well to me, I don't have a SE to test that, though, but in theory it should still connect to it.

For DirectUSB, I don't remember data getting lost.

That's an improvement.
