Fairly straight forward, I upscaled all the textures using ESRGAN (defaulted to 4x) and this is the result. Somethings did need to be removed, specifically the animated textures, as these break when upscaled at the moment, but as far as I can tell, it's unnoticable during gameplay. There are a FEW odd artifacts here and there, but only if you're really looking for them.
Just download it here, or clone the repo and pack it yourself, then load it into OpenGOAL's launcher, and enable it. Couldn't be simpler, and changes should only occur if A. I find something better B. I can add the animated textures down the line or C. the texture layout changes entirely. Other than that, enjoy!
After cloning it yourself, simply zip up the cover, metadata, and testure_replacements folder, then load it into OpenGOAL's launcher like stated in the install step.
This will likely be heavy on your computer during initial install, my system hangs when initially compiling it, but runs smooth as butter once it's done. Expect your computer to choke a little when adding in all the textures.
