Thanks for the response. Regarding my comment about it suddenly opening the terminal, I just now realized that there's a dialogue at the bottom of the screen about it. It's just not that easy to read since it's white text on pretty much a bright background (the edge of the TV).
I actually already read the content of the tutorial and games folder. I just didn't know what else to do in the terminal. But, with your guidance, I was able to get to the next sequence and found the 3D part. The cursor there is indeed a little bit off but not by much. I can still see where I'm going. From there I can finally get to the ending. The story there is nice, though I think some parts of the text got cut off by the screen, which is unfortunate.
