I was fooling around when I managed to unlock all of the breeding doors... Gotta say. I love that you put that in there.
I just modded my save file to give myself more cards to unlock the floor doors, I just used https://www.saveeditonline.com/ for it
you're talking about the doors with the teleporters nearby though right?

just a warning, there aren't any scenes for the ones that aren't already unlocked so there's really no point in unlocking them
edit: I used https://www.saveeditonline.com/ for it, btw the file is called sys.fbf
