Suyu is a self-proclaimed 'successor project to the world's most popular open source Nintendo Switch emulator Yuzu' and was announced on March 5, 2024, the day after Yuzu agreed to pay damages from Nintendo and ended its release. This is a project that has started.

Suyu is written in C++ with portability in mind, and they plan to actively maintain builds for Windows, Linux, and Android. Suyu's developers say: 'We do not support or condone any form of piracy. To use Suyu, you need an actual Nintendo Switch key and a legally obtained game. We do not support or condone any form of copyright infringement. I have no intention of making any money or profit.'
Sharpie, a contributor to the Suyu project and a moderator in the Discord community, said, ``Suyu is currently in a legal gray area, and we are working hard to get out of it.'' He spoke to the media Ars Technica.
According to Sharpie, Suyu is a project that was born out of a 'passion for Nintendo Switch emulation' and a desire to 'not see years of great development by the Yuzu team go to waste,' and the copyright infringement that befell Yuzu. A carefully designed approach is being adopted to avoid the outcome of litigation.
Suyu's development team consulted 'people with legal experience' and 'decided to avoid any monetization.' The project page on GitLab also clearly states, ``We do not intend to make money or profits from this project.'' This is in response to Nintendo's copyright infringement lawsuit against Yuzu, which pointed out Yuzu's profitability. Ars Technica points out that it is clear that this is a countermeasure.
Also, Suyu does not seem to offer a ``step-by-step guide on how to play copyrighted games'' like Yuzu did, and the reason for this is that ``this kind of guide 'It would be like admitting infringement and condoning copyright infringement by others using emulators.' The existence of this guide was also the main focus of a copyright infringement lawsuit by Nintendo.
The first rule on Suyu's Discord community is 'No copyright infringement,' which includes all talk about downloading games, requests for system files, ROMs, encryption keys, shader caches, and leaks. It seems that it will include discussions about the games that have been played. In addition, even if the word 'copyright infringement' appears, you will receive a warning on the Discord community.
According to Mr. Sharpie, although Suyu is based on the Yuzu source code, ``work is underway to remove all references to Yuzu and Tropic Haze (the developer of Yuzu)''. On a technical level, it is said that certain digital rights management (DRM) circumvention code has been changed to avoid legal liability.
Furthermore, regarding the game-specific encryption keys used when running the emulator, 'One of the key parts of Nintendo's lawsuit was the generation of title.keys (encryption keys) by Yuzu, which we first removed. 'It's one of the components. With Suyu, users need to obtain their own title.keys, prod.keys, and firmware from the Nintendo Switch itself,' Sharpie said. However, he also says, ``There is no way to verify that the encryption key was legitimately dumped from the user's Nintendo Switch.''
Suyu's project page has already been set up on GitLab, but the emulator cannot be downloaded at the time of writing. When I click the download button, I get a message saying 'Suyu is not ready yet.'
'The size and growth of the Discord server is much higher than we had hoped, at least until we can figure out what we need to do to keep this project alive,' Sharpie said of Suyu. We wanted to keep a low profile. However, at this stage of development, we have already achieved far more recognition than we could have imagined. Still, the popularity of the project has definitely helped. We believe we have the right opportunity to gather the experienced developers needed to succeed.'
