yuzu reached in-game on several Nintendo Switch exclusives in November 2019, and has been improving in compatibility by the day with active developers ever since.
The Binding of Isaac: Afterbirth+, Puyo Puyo Tetris, and Cave Story+ were the first games to boot. In late April 2018, yuzu booted its first Switch exclusive, 1-2-Switch. Three months later, yuzu was able to run its first 3D rendered game, Minecraft: Story Mode.
This progress report from July 2018 details the extensive work required to research the Switch and get yuzu up and running, chronicling the compatibility status of a small bundle of games and apps over time. The post also covers a surprising number of similarities between the hardware and firmware of the 3DS and Switch, and why portions of Citra were reused in yuzu.
yuzu started showing some 3D rendering on Super Mario Odyssey in early August 2018. This long-awaited exclusive brought a lot of interest in the project. The team covered all the changes that month in another progress report from September 2018.
In May of 2020, multicore CPU emulation was implemented, improving framerates on many titles. This feature appears to cause audio slowdown, so the developers recommend enabling audio stretching in order to mitigate it.
In July of 2021, yuzu's shader decompiler was rewritten, allowing the generation of pipeline cache for Vulkan users and providing a considerable performance boost.
