I'm trying to extract the script for this VN that I'm playing right now, but I can't decrypt the files.
It uses YU-RIS engine (I'm pretty sure) and I've been able to extract the .ypn files from the .yps, but when I try opening the .ypn files, they are completely encrypted.
Please help me.

P.S. If you could, please teach me how to extract it too.
