There are 2 homebrew apps you find on OSC (Homebrew Browser) called "Pair my DS3" and "Pair my DS4" which modifies the Wii to connect to DUALSHOCK 3 & 4 controllers. I never tried but i'm sure it works with Wii games.
It's not the movies or games downloads that I would worry about, like breaking into networks, downloading encrypted things, spying on network traffic. I have seen so many "Top Secret" seals on files when I was a kid
I was obsessed with finding UFOs, a surprising amount of US files where stashed on computers in other countries, China back in the early 90s omg sooo much
