Chaos Rings (CR1:U): HD textures.

  export/  the game writes the pictures to upscale here: run it with --export-textures
  hd/      the upscaled pictures it reads: python3 tools/hd_textures.py <this folder's parent>
           (waifu2x / Real-ESRGAN; tools/ is in the source repository)

With textures/hd/ here, HD Textures is on by itself. Personal use only: they are made from
the game's art. The README's "HD textures".
