Hello SplatPIka,
Are you playing on PC or Android? You can try to change the Backend renderer on CPU settings on Vita3K this can cause more longer loading but can fix some visual issue
Hope that will fix your issue and wishing you a good day!
The game don't work at all? Or it works with some lag?
To make it work properly you need to download 2 other file after Vita3K
If that can help to make it work you can also change graphics settings before starting the game on Vita3K
If none of that work can you give a feedback and give all your phone specification? That will help to do future update and make a better compatibility
