Shader cache included in this repack for improved game perfomance. With next Cemu updates just unzip new version to “cemu” folder, saving keys.txt and settings.bin files just in case.
The current version of Cemu allows to play Mario Kart 8, but there bugs (like flickering and audio bugs) and perfomance is not the best side. If you become a patron on Patreon – you will receive access to early betas before public release. New Cemu versions are released on Cemu official site. Just download this release, install as any other PC game and run it from desktop icon, created by the installer. 4-cores CPU + good GPU are highly recommended. But even now, with Cemu v1.7.5d you can play Mario Kart 8 game on your PC, if it’s not an abacus.
