These videos represent casual play. By no means am I (1) an expert at this game or (2) intending to complete all secondary or bonus objectives.
The briefing and debriefing sections originally were (320 × 200) px × 70 Hz, but were upscaled (nearest-neighbor) and padded to the native resolution of the mission sections ((640 × 480) px × 70 Hz). If you want the videos to be bigger than that, use ffmpeg or ffplay to scale them up yourself—for example:
ffplay -sws_flags neighbor -vf "scale=h=1080:w=-1" 000024.webm
