Dolphin, the GameCube and Wii emulator - Forums

Hey there i am currently modding starfox assault *my favorite gamecube game* and am wondering if it's at all possible to change the video files into 4k upscaled versions ? i know you can extract the files from the games iso and tinker with it so is it possible?

No, not in any practical manner. The files can be extracted and upscaled but they can't be added back into the game directly (as 4k resolution is much too large for those old systems) and Dolphin does not have a capability to replace videos with higher resolution ones like it does textures.
