I would like to add, to get this to work with retail carts:
1: boot into gateway mode (not classic mode) normally.
2: remove your gateway card from the system.
3: insert your retail cart and then press select.
4: after the menu appears, press B and wait like 5 seconds.
5: after the cart appears...
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
