Can we use the 5.8 art in the 6.x version?
Someone linked a pictures folder a few pages back that you could place in the game folder and overwrite the new pictures. I'm not sure if they did it manually or it was left that way by the devs for coding reasons, but the original images and AI images used the same file names.
As for whether or not it works; the AI art is upscaled so the old pictures don't fit the screen completely. They did still work though.
