Re: [ONEONE1] MATRON ―監獄島の巨乳女看守―
Yeah I tried that save before posting but it had the same scenes I did. The CGs for that ending are most likely the ones where the heroine is getting fucked on a bed.
I think the flag is most likely a scene where she gets raped after beating Iron, and where you have a choice on wether she holds out or just fully gets into the sex. But I don't know if other things (like number of sexe scenes and title) matter as well. That uncertainty and having to replay the last quarter of the game kinda keep me from trying.
I figured you tried that one already, but doesn't hurt to ask, everyone overlooks things on occasion.
I will look into it in RPGMaker, that info gives me somewhere to start at least. I would also rather not play through the whole game again trying to figure out what triggers it.
EDIT: Looking into it, I think you have to beat the game on NG+ to get that ending, that is the requirement for unlocking that CG anyway. According to the script that controls the CG menu.
