透明通道图片 → 像素素材(sprite)：精确面积覆盖率 + 核心像素取色 + 细结构救援，硬边 alpha 与调色板硬上限。Alpha-aware pixel-art downscaler: exact fractional-grid coverage, core-pixel sampling, thin-structure rescue.
Full-motion video on a stock Neo Geo AES. An offline baker interns every 16x16 tile into character ROM, so the 68000 player only pushes tile numbers into sprite control blocks. Ten minutes at 59.2 fps with sound in a 158 MB cartridge, verified bit-exact against geolith and MAME
Convert bounded RGBA PNG fixtures into deterministic indexed palettes using exact integer error accounting. Real libpng output is checked through independent decoding, palette and packed-row oracles.
Speedrun project (20min 40s): ComfyUI custom node that converts images into ZX Spectrum-style graphics based on the functional code of Spectrumify
