Quick answer: Early copies of the Switch 2 Ocarina of Time remake were dumped around launch, and Lichii emulator forks already boot it on PC. Reports put gameplay around 15–30 fps with visual glitches, while some areas run higher. Nintendo has not commented on the emulator footage.
The Legend of Zelda: Ocarina of Time remake is already showing up on PC through early Switch 2 emulation. Notebookcheck reports that early-shipped physical copies were dumped around launch via the existing ns2jb userland jailbreak, and multiple clips show Lichii forks booting the remake before or right as the November 5 Switch 2 release landed.
Playability is early. Wccftech puts typical gameplay around 15–30 fps with visual glitches. Notebookcheck describes stuttering, frame rates swinging from about 20 to 60 fps, and washed-out colors. DSOGaming says the open-world areas still have flashing artifacts and bloom issues, while the Great Deku Tree looks more stable. Separate clips they cite show roughly 40 fps on a high-end Intel/RTX 4090 rig and up to 60 fps in that Deku Tree section on a Ryzen 7 9800X3D with an RTX 5080 using one community fork. The mainline Lichii build may not support the remake yet; forks are what people are testing.
For handheld and PC players watching the Switch 2 scene, this is a status check, not a ready alternative. Performance and image quality are not console-like, and Nintendo has not commented on the emulator footage. The company had already reportedly pulled SmileBASIC 4, the earlier ns2jb entry point, from the eShop. Where this goes next for handhelds later depends on how far the emulators get and how Nintendo responds, the same pattern the Switch 1 scene went through.
