Dangerism's Muramasa: The Demon Blade Texture Pack

Dangerism put every texture in Muramasa: The Demon Blade through ESRGAN at four times the original size, stripping out the noise and dithering along the way. Vanillaware’s hand-painted art comes out clean and sharp, and the pack is aimed squarely at 4K displays.

Later updates switched to a new upscaling model with crisper detail and stronger contrast, and the most recent one adds a model trained just for the sprites of the two leads, Momohime and Kisuke. These later versions keep an unblended look that differs from the softer first release, so players who preferred the original style may find the change less to their taste.
