I had the same problem as you do. I fixed it by using dmbooter and lemme tell you i'played many games and not error so far. I use an sd card coneccted to an card adapter wich is useful since you can use 64kb that gives you better access writing speed.
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
