Giodude's Sonic and the Black Knight Texture Pack

Giodude replaced almost every texture in Sonic and the Black Knight with versions upscaled through ESRGAN (the 4x-AnimeSharp, 4x_BSRGAN and 8x_NMKD-Typescale_175k models) and Gigapixel. The HD textures can be downloaded here as PNG or as a smaller DDS set.

The original release also offered a graphics mod that sharpens or removes the low resolution bloom (the same fix made for Sonic Colors), swaps the Wii Remote button prompts for Xbox Series X ones, and comes with a matching Dolphin controller profile. Those extras were separate downloads from the texture packs.

How to set it up

1. In Dolphin, open File > Open User Folder, then go into Load/Textures/.
2. Extract the download there, so you end up with a Load/Textures/REN/ folder.
3. Open Graphics > Advanced and tick Load Custom Textures. Ticking Prefetch Custom Textures too stops stutter, if you have the RAM for it.
