Reallive prioritizes files named seenxxxx.txt.
It’ll follow the main seen.txt’s script until a scene ends and seen.txt says “go to seen0200” it’ll first look for a seen0200.txt, and if one doesn’t exist it’ll look inside the seen.txt file for that seen.
So just throw them in the same folder as reallive.exe and seen.txt, and it’ll work perfectly. If you ever want the H-scenes back you can just remove the numbered seen.txt files.
Just make sure you don’t save during the night-time activities in Kano’s route, or when Yukito pretends to be a cat.
