yuzu is a work-in-progress Nintendo Switch emulator. yuzu is an open-source project, licensed under the GPLv2 (or any later
version). yuzu has been designed with portability in mind, with builds available for Windows, Linux,
and macOS. The project was started in spring of 2017 by
bunnei, one of the original authors of the popular
Citra 3DS emulator, to experiment with and research the Nintendo Switch. Due to the similarities
between Switch and 3DS, yuzu was developed as a fork of Citra. This means that it uses the same project
architecture, and both emulators benefit from shared improvements. During the early months of development,
work was done in private, and progress was slow. However, as Switch reverse-engineering and homebrew
development became popular, work on yuzu began to take off as well.
In January of 2018, the yuzu team was formed out of several Citra developers, and the decision was made to release the project
publicly. As an emulator, yuzu is in its infancy, and is only currently useful for Switch reverse-engineering
and homebrew development.
