Cemu - Wii U 模拟器 - Switch 移植版

# Cemu-nx — Nintendo Switch

An unofficial homebrew port of the Cemu (Wii U) emulator to Nintendo Switch, with an all-in-one SDL launcher, cover-art library, per-game settings, graphics packs, controller remapping.

## Features

- **Cover art** — auto-download from SteamGridDB
- **Per-game settings** and graphics-pack configuration
- **Controller remapping**, multiplayer input, gyro and vibration
- **Joy-Con Amiibo scanning**
- **TV and Wii U GamePad audio**
- **Hardware H.264 decoding** through Averne/FFmpeg
- **SD, USB and SMB storage support**
- **Game, update and DLC installation and management**
- **Experimental Pretendo and custom online-service support**
- **WUA, WUD, WUX, WUHB, RPX, ELF, ISO and extracted-game support**

## Renderer

- **Vulkan (NVK)** — @dantiicu

## Notes

- Launch through Homebrew Menu in **full application/title-override mode**, not Album mode.
- Place the nro `sdmc:/switch/Cemu/` and your keys in `sdmc:/switch/Cemu/keys.txt`.
- First-time shader compilation can cause stuttering or long pauses. Later runs should be faster.
- Press **L + R + Plus** during gameplay to open the quick menu.
- Game compatibility and performance will vary.

Should be frontpaged!
Damn, you're on fire. I'll try BOTW asap, lol.

stupid question but how are you supposed to store games on the sd card, as the format mostly used by switch sdcards is FAT32 and wiiu iso are way larger than 4gb?

USB Flash drive / HDD formated in Exfat is supported on the launcher

then I suppose it's meant to be used docked, handheld mode should run like shit?

It's meant to be used with overclock, docked or handheld doesn't really matter

how on earth are you finding the time to do all of this, hot damn

@Nagaa
Thank you very much!.. My beloved «Duck Tales Remastered» works silky smooth in 60 fps!..

@Nagaa take a bow man!

However... I get an Atmo panic when trying to run Wind Waker HD. Can't get to title screen after initial load screen

Using unpacked version of the game if it helps and loading from HBL and from a forwarder

What overclock settings do you recommend for running Zelda: Wind Waker ?
I tried running it as-is, but I just keep getting an atmosphere crash.

How is the gamepad handled? Or is it not at all?

I can finally play Pikmin 3 on Switch.

Fantastic work. Don't suppose you can create game shortcuts to launch games from the switch home screen? @Nagaa

Awesome work! Does it have mod support? I want to try out the mod that makes Color Splash not garbage

try with WUA / WUX format and make sure to have keys.txt, i didn't really tried any unpacked games yet it may have issue

2193 CPU / 2400 RAM Minimum
For the GPU it depend on the resolution 900p - 1228MHz / 720p - 921 MHz
Disabling Vulkan Accurate barrier can increase performance but can cause graphical issue in some games

Games that rely on the gamepad screen are not supported

You can, i show it in the video

It's supported, but the fix for Color Splash didn't seem to work for me and it was still too dark

The youtube video shows the emulator doing just that

And now we have WiiU emulation running on the Nintendo Switch.

See what happens when you finally move onto a dying system? The members of the homebrew scene will finally shed light to it and will deliver the impossible onto the system people initially thought was starting to lose the quality that the other systems had. Seeing this really makes me look forward to what happens with the Switch 2.
