man... believe me i've tried. even when i got to making it work with lutris, and it all booted up perfectly, there were still some minor things missing. Some sound and visual effects were absent, and I just couldn't play without them lmaoo.
I eventually just gave up and decided to dual-boot my steamdeck into Windows. Works perfectly on there. Plus, i set up a basic cloud save thing between my pc and sd, so i can just sync files and keep playing on either one.
This is what i initially followed to get everything running. you've probably seen this already, but just to share in case:

^^ For that, I'm pretty sure I did the visualnovelengine. The whole thing might look tedious, but it's surprisingly simple. Hope that helps.
glad to know i'm not the only one who thought to put Kamidori on their sd tho lol
