Clarified early days of the switch emu pioneers. Cleaned up speculative & subjective verbiage in yuzu, Ryujinx, SphiNX, and Egg NS sections, consolidating information to only contain factual statements.
While Nintendo intended to step up the security of the console, vulnerabilities were still found early on that allowed tons of system files to be dumped, including dumps of games in the form of romfs.istorage archives, an exefs folder, and license files. These game dumps eventually got shared online by scene groups except for their licenses but were missing important files to run and even if they had been completed, there were no custom homebrew apps let alone solutions to load unofficial game dumps for the system. A number of prominent hacking teams (starting with shuffle2 and fail0verflow in collaboration) all came across a new exploit independently of each other that allowed complete control over the system, later officially recognized by Nvidia as CVE-2018-6242.
A "debugging emulator" for the Nintendo Switch, CageTheUnicorn (now [https://github.com/reswitched/Mephisto Mephisto]), popped up not long after the first components were dumped. It was designed to emulate sysmodules with "no support for graphics, sound, input, or any kind of even remotely performant processing [...] by design". It was then revealed that A couple of months later, members of both the [[Citra]] and [[Dolphin]] teams were already working on announced the release of [[yuzu|their own emulatorwritten in c++]] in secret, followed by another which was capable of booting some homebrew applications; almost simultaneously, developer releasing gdkchan released an emulator written in c# named [[Ryujinx]], which was capable of booting commercial Switch game Puyo Puyo Tetris.
==Emulators==
;[[yuzu]] <small class="plainlinks" style="font-weight:normal;">([https://yuzu-emu.org/game compatibility])</small>
:An open-source emulator made by many of [[Citra]]'s developers. It advanced so quickly the team had many games working fully in a matter of months. As it is a hard fork of Citra it shares many of its traits, namely cross-platform support and the use of OpenGL (though unlike Citra it also supports Vulkan). Top-tier hardware is required to get decent speeds in most games at the moment; many Many 2D games now render graphics properly and at good speeds, ; many 3D games are playable with some even reaching full speed, and a lot of exclusives are playable already but can't be considered perfect yet. The development team continually works to improve compatibility and accuracy, and This emulator currently offers paywalled early access builds that introduce new features early through to $5/month [[Emulators on Patreon|Patreon]]subscribers which allows them to utilize new features prior to their release on the mainline build. One of yuzu's most notable features is its disk-based shader cache for OpenGL, negating the need to compile shaders on the fly.
;[[Ryujinx]] <small class="plainlinks" style="font-weight:normal;">([https://github.com/Ryujinx/Ryujinx-Games-List/issues compatibility])</small>
:Another An open-source emulator that's programmed in C#. Most 2D games are now booting and running at comfortable speeds and many 3D games are playable. It also supports resolution upscaling to 4K and beyond; custom upscaling/downscaling ratios are supported. Unlike yuzu, Ryujinx does not yet have a disk-based shader cache, making the first few moments of gameplay suffer from stutters in certain games. Ryujinx does not offer early access builds; however, it is still possible to test newly developed work-in-progress features can still be tested by using pre-built Appveyor packages, or building locally from unmerged pull requests. Separately, there is now Ryujinx has released a special closed source LDN-enabled preview build supporting local wireless multiplayer across the internet.
;SphiNX
:A closed-source emulator that's been in the works since late July/August 2018. It can boot some homebrews as well as the title screen of one commercial game. Seems The project appears to be a one person project for personal training more than a fully fledged community projectdead at this time, with no known updates in over two years.
;Skyline
;Egg NS
:Claimed the first spot in getting games running on Android. 81 titles are known purported to work, and the rest are either not working or assumed to fail. That's about it There is significant controversy surrounding this emulator for positive things; the following reasons: the current version lacks any onscreen buttons, and instead forces requires users to purchase a specific controller. It also ; it expects to run on a high-end device within the ballpark of a Qualcomm Snapdragon 855/855+/865/865+. Combine all that with users needing to log into their service to use the emulator, and you can imagine there was quite a controversy. The fact that ; it was eventually discovered to have lifted violated GPLv2 licensing requirements by using code straight from yuzu (which uses in a license with [[Licensing#Definition|stronger copyleft conditions]]) did not helpdisallowed manner.
