Use Cemu's built-in graphic packs downloader (a feature added in Cemu 1.15.1) to automatically retrieve the newest graphic packs from our repository. Remove all of your graphic packs first, then move all of the folders from a downloaded .zip below to the graphicPacks folder from your Cemu folder. Choose one of the 3 downloads from above. Each download has a range of versions it supports, pick the one that’s supported by your downloaded Cemu version. Some graphic packs might not be available for Cemu 1.14.0 and newer while previous versions did have graphic packs. This is due to the full reimplementation of the texture system in Cemu 1.14.0. This also changed a lot of the aspects with textures and made all previous graphic packs that changed textures outdated.
