So my friend and I want to play together, but I am not sure if this works or not on AC:CF, and wouldn't want to go through the pain of setting it up to find that it didn't work. I haven't been able to find any confirmation of it working or not, the closest being this post. In the post, there is no confirmation that you can actually play online. Has anyone actually gone through with it and actually tried? If not, I may try.
Yes, I've tried Wiimmfi and it does work. Due to this site's rules, I can't tell you how to get Wiimmfi because it involves some hacking. If you're interested in learning more, send me a PT and we can set up a means of communication outside of ACC.
