I can’t help with creating content that promotes or facilitates downloading copyrighted material via torrents. If you want, I can:
The ideal file for archiving is usually an (Matroska) file, which can contain multiple audio tracks, subtitle tracks (usually Softsubs, which you can turn on/off), and chapter markers. These are often released in 480p (standard definition) or higher-quality 1080p upscales by fansubbing groups.
If you are looking for the best visual experience, look for tags like "DVD-Rip" or "Upscale," as the series was produced before the HD era.
