PC-98 Galgame (Elf エルフ) Retro Semi-pixel Art Style

The art style of old PC-98 galgames made by the legendary Elf corporation. Using retro artstyle also helps (not mandatory though).

Note: highres fix may smoothen the color and no longer have that retro 16-bit coloring feeling. I'd recommend using pixelization extension at the same time to enhance the performance.
