My favourite experience regarding Wii homebrew so far has to be NetBSD. I wanted to use my Wii as a computer for a while now, and NetBSD being available as an operating system you can install and get going on an SD card and a Wii with the HBC is definitely the highlights of my Wii homebrew experience. I don't use my Wii much at the moment, as I don't even have a monitor I can use for my Wii yet, but I have used it for a while on a TV and it was nice.
Networking is a bit hard, at least on the Wii however. I tried to get WiFi included in as a Wii image of NetBSD to burn, this was during my time on FreeBSD, and I just couldn't compile it. I was doing something weird where I would alternate between GCC and clang but that would have been a waste of time once it got to booting.
Other than that, it was nice writing a fetch program entirely written in C using vi and man pages to get by. It was a nice break from writing things without an LSP to help, although I still love using modern features many editors provide, obviously excluding AI, so I will stick with that. I also found that Lua existed on it which definitely helped whenever I didn't want to write C.
First *BSD post in a while, as I forgot to talk about the time I used NetBSD. I'll probably talk about Linux more at some point but I wanted to talk about *BSD a little again. Try NetBSD if you get the chance!
