Finally, we can dump and replace textures in Citra. I am fine with the original art but I really hate how UI and fonts scale up in high resolutions, especially in Pokemon games, so the experience is going to be much better, at least for me. I hope we can use AI upscaling tools like ESRGAN and Waifu-2x to upscale art, it will be much faster to create packs.
This is currently WIP and it is only available in experimental Canary builds so it will probably take some time to get into official builds.
