Unless you have serious trouble with English, a video guide doesn't help much with these games. 90% of the Zero Escape games are cutscenes with a choice in every few hours (unless you skip the story). Aside from a few exceptions the solutions for the puzzle rooms are just a list of things you need to do. This site has guides for both games in a simple manner:
https://www.thonky.com/nine-hours-nine-persons-nine-doors/th...To get all the achievements in the first game, 999 you have to go through every room/novel in the flow chart. The built in flow chart will indicate how to get additional endings by following the same colored route. The only "secret" in it is you have to pick certain answers in certain rooms (the flowchart shows those as well).
The second game VLR is essentially the same (complete the whole flowchart) but with much more routes and if you care about the story you should finish the two longest routes last. Also you must play VLR on hard (default setting) for every achievement (collect the secret gold/hard files as well in every room).
If you don't care about the story then you can enable SKIP from the options from the start, skip every story bit and do the rooms with the guide in a few minutes. I'm pretty sure that is why the game has such a low ratio. If you care about the story then the game is a good 50 hours even with a guide and reasonable skipping (if you watched a scene you can skip it on replays even if the main "skip everything" option isn't enabled in the main menu).
