Granted I know jack all about coding and VN developement but i have to imagine the simplest option would be to have a narrative interlude come up whenever a past choice becomes relevant that gives a memory jog for any who have forgotten and then asks them what they did.
Like, if the scene requires the player to identify what they did with JD put an image of that pathetic loser up(to jog memory for those with a more visual-based memory) and a breif description written as if the MC is remembering.
Example:
"Yeah. I remember that little limpdick JD. He was Jessy's wannabe Stepdad and in an open relationship with her mom. What we didn't know at the time was he was blackmailing Jessy for various sex acts. He never got her virginity but it wasn't for lack of trying. Once we found out about it we dealt with him once and for all by....
A) Arranging for the sheriff to catch him in the act of assaulting Jessy.(Blue)
B) Luring him out into the woods where Jessy bit his pecker off and I finished him.(Red)"
That seems(to me at least) infinitely easier for you and the players alike, to resolve any questions related to past Chapter 1 Choices.
Granted there's ALOT of past choices but they all seem to end up in the same place anyway, no?
Then again i exclusively make "Gotta fuck 'em all" choices, so what do I know?
Maybe there is an easier(but less satisfying IMHO) option. "The Bioware Approach". Bioware RPGs used to just make a blanket "All lightside choices are canon" or vice versa for their RPGs sequels/followup materials. Completely ignoring the possibility of contradictory Lightside choices. lol.
So you could do something similar where you ask players to decide at the start if they went Red or Blue and that will make all Red Choices or Blue Choices "canon" for that playthrough?
