i have windows, so i just copied the PATCH file from the DLC directly into the bewitching-sinner-visual-novel file. so bewitching-sinners-visual-novel -> BewitchingSinners-1.9.8-pc -> "game" -> copied the "PATCH" into that one, then i went out of the "game" folder and opened the BewitchingSinners from the 1.9.8-pc file, the program one, and it worked lol
