Cartridges are useless except for the joy of looking at them. I have 3 computers for the reason of saftey and losing info. One computer has online out of the three. I keep all my online games on it and some single player games along with music. On my second computer I keep a back up of everything on thier including online website URLs and passwords - offline and unplugged until use for saftey. My third computer has all my single player game backed up and a lot of private work - plugged in but offline.
My online pc has a nice firewall with addware protection, avast, and 4 more custom made things to keep me protected.
Thing is, I have to put one thing on a computer, and then put it on the other two. It’s a pain in the ass, but I never get worried about losing stuff or getting a virus. All I have to do is take the internet out of the main one, then put it in the second one and it’s like nothing every happened. During that time of leasure, I fix my broken one. I’m ideal, ^^
