Nintendo Switch Emulator

yuzu emulator

Special thanks in this version goes to Naii the Baf for creating and providing the first TASing version of Yuzu, and averne for pointing out the perfect location for syncing the inputs! Even bigger thanks to Narr the Reg, who's constantly helping me out whenever some deeper changes in Yuzu's code are required!

If you have any issues with this custom build, ping me (MonsterDruide1) on the SMO TASing Discord.

Setup TAS

Before you can start creating a TAS by your own, you have to match a few settings in the configuration of Yuzu:

1. Open the configuration menu using Emulation -> Configure....
2. On the first page (General -> General), disable Pause emulation when in background.
3. In the config of CPU -> CPU, the accuracy should be on Accurate.
4. (optional) For a small speed boost, you can set Graphics -> Advanced -> Accuracy Level to Normal.
5. Finally, exit out of the config menu and go to Tools -> Configure TAS... on the main toolbar to select the parent directory of your script at the bottom.

Keymap

Hotkey	Description
CTRL + F5	Starts the playback of the selected script file. Make sure to set the Input Device to TAS! (see below, Running TAS)
CTRL + F6	Refreshes the file and resets the playback progress.
CTRL + F7	Record a new script file. See below for a guide on that.
POS1	Activate frame-by-frame (pauses the game)
SPACE	Advance one frame while in frame-by-frame mode

Recording TAS

WARNING: Recording a TAS will override your latest recording!

Start by setting up your location/environment. When you're ready for recording, press CTRL + F7 to start the recording. Now just execute whatever inputs you want to replicate later, and press the keys again (CTRL + F7) once you're done.

During this whole progress, the Input Device remains on a normal setting, like Controller or Keyboard/Mouse.

Running TAS

The script itself has to be placed at the location specified during setup, namely in the file script0-1.txt for Controller 1, script0-2.txt for Controller 2 and so forth.

For debugging the script, you can enable View -> Debugging -> Controller P1 to have an input display of Player 1. This helps in finding timing issues.

Now, before starting the playback, you may want to refresh the file and reset playback progress if you already played a TAS before. Just getting used to always reset before playback will avoid the issue of playing back an older version of the file, if you changed the script while Yuzu was still running.

Press CTRL + F6 to refresh the file, then CTRL + F5 to start the playback.

If you still run into any issues, feel free to ping me (MonsterDruide1) on the SMO TASing Discord.

Default README

yuzu is an experimental open-source emulator for the Nintendo Switch from the creators of Citra.

It is written in C++ with portability in mind, with builds actively maintained for Windows and Linux. The emulator is capable of running several commercial games.

yuzu only emulates a subset of Switch hardware and therefore most commercial games do not run at full speed or are not fully functional.

Do you want to check which games are compatible and which ones are not? Please visit our Compatibility page!

yuzu is licensed under the GPLv2 (or any later version). Refer to the license.txt file included.

For development discussion, please join us on Discord.

Development

Most of the development happens on GitHub. It's also where our central repository is hosted.

If you want to contribute please take a look at the Contributor's Guide and Developer Information. You should also contact any of the developers on Discord in order to know about the current state of the emulator.

If you want to contribute to the user interface translation, please check out the yuzu project on transifex. We centralize translation work there, and periodically upstream translations.

Building

• Windows: Windows Build
• Linux: Linux Build

Support

We happily accept monetary donations, or donated games and hardware. Please see our donations page for more information on how you can contribute to yuzu. Any donations received will go towards things like:

• Switch consoles to explore and reverse-engineer the hardware
• Switch games for testing, reverse-engineering, and implementing new features
• Web hosting and infrastructure setup
• Software licenses (e.g. Visual Studio, IDA Pro, etc.)
• Additional hardware (e.g. GPUs as-needed to improve rendering support, other peripherals to add support for, etc.)

We also more than gladly accept used Switch consoles, preferably ones with firmware 3.0.0 or lower! If you would like to give yours away, don't hesitate to join our Discord and talk to bunnei. You may also contact: [email protected].
