I saw this old thread by Corta (anyone know if they are still contactable btw?) in which they have an edited version of Zone's Reiko Biker Girl game, in which there's extra options for keeping the cum on some elements when replaying.

How exactly is this done if anyone knows? Or if Corta can still be contacted so I can ask them directly (my account isn't letting me reach their page to message them for some reason.
I've been poking around in FFDEC but I cannot seem to figure out how they did this.
