This is the first ending encountered by most gamers if you enter the Dark Omen (floating ocean palace) fight Zeal, the Mammon Machine, and continue on to defeat Lavos. At the ending, cat(s) will run through the time gate right before it closes followed by Chrono’s mother who is chasing them.
This was completed on the Playstation remake of the game found in the Final Fantasy Chronicle title. Even though this was played on my Playstation 2 it still suffers a bit from extensive load times. They have some added anime scenes throughout the game and at the ending which kind of makes up for some of the shortcomings.
I plan on showing the other ending of Chrono trigger as I go along and progress into “Game Plus” mode. When I do these recordings I will show everything from the save spot which includes the fight with Lavos, over and over again. This might seem tedious for most viewers so I will also place a timestamp in the description that you can use to forward to the ending itself on the video.
