Good morning. Viewing that video you posted that is not a crash and has nothing to do with your video card, but I did not specifically test under Linux. Note: It is imperative that the folder structure remain as noted in the OP installation:
Code:
(ThisTitleName) folder/
├── game/
│ ├── SanchoMod/
│ └── (support files)
├── lib/
├── renpy/
└── (ThisTitleName).exe
If the SanchoMod folder is not located under the VN's "game" folder or it is otherwise modified (decompile/rename) it will not work.
Can you please verify the above and report back?
