For retro fans, this is a signal that the digital preservation of Nintendo classics has entered a golden age.
The key to success was years of work to fix specific graphic and sound errors in complex projects, such as Star Wars: Rogue Squadron. Thanks to optimization and modern APIs (Vulkan/Metal), Dolphin now shows games with accuracy higher than the original, in 4K, with anti-aliasing and stable 60 FPS where the original "slowed down" at 20.
The novelty is useful not only for powerful PCs, but also for portable devices, including Steam Deck and Android. Dolphin has become lighter and more economical, allowing you to play Metroid Prime or Super Smash Bros. Melee on the road without overheating and rapid battery discharge.
This is an example of the power of open-source: thousands of volunteers polished the code to preserve Nintendo's legacy. In an era of mediocre remasters, Dolphin shows how to respectfully preserve the history of video games.
