Design a brand-neutral 1990s 16-bit console-era game poster for an original young-adult impish heroine named Lilim Lily. Make it feel like a dramatic retro action RPG advertisement from the cartridge era without using any real console names, publisher logos, licensing badges, or trademarked platform marks. Use a wide 16:9 poster layout: a large central anime-style heroine portrait with silver twin-tail hair, small bat wings, gothic fantasy accessories, a mischievous but non-explicit expression, and a purple moonlit castle background. Surround the main portrait with small pixel-art gameplay screenshots, character-expression panels, decorative gothic frames, Japanese-style promotional text blocks, and a bold fictional game title logo. The mood should be dark fantasy, playful, nostalgic, and premium, blending glossy anime key art with retro 16-bit RPG packaging design. Keep all characters clearly young adult, avoid childlike proportions, and keep the styling non-explicit. Output aspect ratio: 16:9.
