ChaotixSoda's Sonic Heroes Texture Pack
By ChaotixSoda
This project is a complete AI HD upscaled texture pack for Sonic Heroes on the GameCube. Using AI restoration techniques, I’ve cleaned up and enhanced the game’s original textures to create a sharper and more detailed look, while staying faithful to the art direction Sonic Team originally intended. I also replaced the HUD & UI textures with HD versions from the 4X GUI mod on PC, and adjusted them to work with Dolphin.
The goal here is to preserve the early 2000’s Sonic Heroes aesthetic as closely as possible, while also boosting the game’s texture quality beyond original limitations. As such, this mod is meant to be an HD refresh, not a complete redesign to modernize every aspect of the game’s visuals. I used a variety of AI models across the entire game to achieve a cleaner and sharpened look with less artifacts. The results turned out nicely and are a noticeable upgrade over the low-res, compressed textures from the original game. Sonic Heroes fans who enjoy playing on GameCube will find this Dolphin texture pack an easy way to experience the game with HD treatment!

How to set it up
- In Dolphin, open File > Open User Folder, then go into
Load/Textures/. - Extract the download there, so you end up with a
Load/Textures/G9S/folder. - Open Graphics > Advanced and tick Load Custom Textures. Ticking Prefetch Custom Textures too stops stutter, if you have the RAM for it.
