Cemu
Accuracy
Performance
Features
Cemu is a closed source emulator for WiiU which is considered to be in experimental state. That said, it's able to play quite a few number of games very smoothly without major issues and graphics packs can even be injected into games. Please check compatibility list for more details.
Extensions:
GamePad input source override for cemu, including full motion sensing support (requires additional software, see the guide)
Adds code/data patching to your games at load-time, which you can activate and share the same way you do graphic packs!
Think of it like a pcsx2 plugin, implementing something not in the core
Community Graphic Packs which is used to upscale and change your Wii U games
Allows the Nintendo Switch Pro Controller, Joycons and SNES controller to be used with the Cemu Emulator and System-Wide

Most Recent Changes
--1.26.1--
Lots of Input fixes:
Improved keyboard handling (Shift and other special keys can be mapped and used again)
Better handling for controller connect/disconnect. The UI will now update accordingly
Improved rumble for Gamecube controller API (#596)
Fixed an issue where the currently active controller profile file (controller<Index>.xml) would be deleted when the game profile set a different profile
Restored DirectInput under Wine
Fixed threading issues causing random crashes, usually these would occur when interacting with the input settings in some way
Fixed an issue where a rumble strength setting of 0 wouldn't completely disable rumble on some input APIs
--1.26.0--
New in 1.26.0c:
input: Fixed an issue where the special buttons "blow mic" and "show screen" would permanently get stuck in pressed state
misc: Added a workaround for Cemuhook custom timers crashing
New in 1.26.0b
ErrEula: Fixed an issue where ErrEula message box buttons were not clickable
coreinit: Fixed a potential internal state corruption in OSCondWait
This resolves Tekken Tag Tournament 2 freezing on boot
misc: Optimized speed of texture dumping feature
New in 1.26.0
input: Reworked input system from the ground up, fixed bugs and added new features
Input configuration now supports binding more than one controller to any emulated controller
For example, you can setup two joycons to work as one controller
Or you can setup an XInput controller and then add your phone as a DSU motion source
Any combination is possible with no limit on how many input sources you can set per emulated controller
This update also features a new profile system and overhauled UI to accomodate
for the new multi-controller feature. Cemu remains backwards compatible with existing controller profiles.
Additional input improvements include:
SDL API now also supports Stadia, Steam and Amazon Luna controllers
Default button layouts for some API/controller combinations
Much better support for native Wiimotes
Generally better handling for deadzone on all controller APIs
general: Fixed a long standing crash issue that could occur when opening any file dialog (like MLC folder selection, or file load option)
This likely also fixes other rare UI related crashes
general: Fixed an issue where the download manager would always download v0 of any DLC instead of the latest version
Vulkan: Fixed random graphic corruptions that could occur due to incorrectly handling some Vulkan pipeline configurations
Resolves graphic glitches in Bayonetta 2 and possibly other games
AX: Unimplemented AUX audio effects are now handled gracefully
This avoids issues like echoed audio seen in a few games since Cemu 1.25.3
AX: Store AUX channels as 16-bit samples instead of 24-bit to match console behavior. Some games require this in order for their effects to be applied correctly
Fixes distorted background music in Color Splash
log: Reworked path printing to match the actual internal paths Cemu uses (for mlc, base game directory etc.)
Also fixed log encoding issues with non-ANSI directory names
gfxPacks: Fixed several issues where replaced games files as part of a graphic pack would not be detected correctly
gfxPacks: Improved robustness and logging of graphic pack errors. Cemu should not close when encountering some types of graphic pack errors
CPU: Tweaked the thread scheduler to prevent a rare but repeatable type of deadlock
Prevents Mario Party 10 from getting stuck on boot
RPLLoader: Reworked large parts of the RPL loader internals, fixed bugs and improved robustness
Partially broken .rpl files as encountered in some homebrew should no longer crash Cemu
Fixed an out-of-resources related crash seen in Mario Party 10
coreinit: Release held mutexes when a thread is ended
Fixes Mario Party 10 minigames getting stuck during loading
UI: The game loading-screen image will now stay at the correct aspect ratio regardless of the size of the window
UI: The "Save main/pad window position" options will now correctly remember and restore the fullscreen state
UI: Decreased the minimum allowed size of the GamePad window when resizing
misc: Fixed an issue where transferred NNID accounts could not be used with the Download Manager
misc: Reworked the code used for parsing INI-format files for better performance and robustness against syntax mistakes and BOM-sequences
The INI format is used by game profiles, controller profiles and graphic packs rules.txt
debugger: Data directives like .float or .int now also work in the debugger assembly view
--1.25.6--
general: The download manager now has experimental support for downloading DLC
Online features require dumped system files. See the guide at:
https://cemu.cfw.guide/online-play
Vulkan: Fixed an issue where asynchronous GPU operations could get stuck indefinitely
Lego Batman 3 should no longer softlock on Vulkan (#495)
Vulkan: Reworked command buffer scheduling to decrease latency between CPU and GPU
This can improve performance on some systems
GX2: Correctly emulate timestamp submission in GX2DirectCallDisplayList()
Some games, like Bayonetta 1, rely on this behavior and should run much more stable now
UI: Fixed an issue where the game list would not track play time
--1.25.5--
New in 1.25.5b
Vulkan: Partially reverted new synchronization model due to worse performance on some drivers
Also fixed a general synchronization issue that could lead to flickering graphics and various other defects
UI: Tracking of play time should work correctly again
gfxPacks: Fixed two regressions related to label processing in assembly patches (#574)
New in 1.25.5:
CPU: Added option to control the speed of the emulated CPU timer, similar to the functionality offered by Cemuhook's custom timers
Vulkan: Reworked internal synchronization
This fixes some pixel flickering artefacts. Known occurrences:
Some waterfalls had tiling artefacts in Breath of the Wild
Shadows would flicker in Pac-man and the Ghostly Adventures
AX: Implemented audio AUX bus mixing correctly
Some games use this feature for reverb or similar audio post-processing effects
The changes below are mainly of interest to graphic pack developers:
gfxPacks: Fixed various issues related to assembly patches
Alignment behavior is now consistent across all gfx pack versions
Automatic alignment. Cemu will automatically insert padding to keep the alignment intact (.align directive no longer required in most situations)
Fixed wrong encoding of CR operand in cmpw/cmplw instruction
debugger: Double clicking an entry in the debugger module window will jump to its base address
debugger: The debugger register view window will now correctly show the state of the CR register fields
--1.25.4--
Vulkan: Avoid internal hash collision related to pipeline lookup
This fixes a bug where, under very rare circumstances, draw operations would render with the wrong parameters
Seen in Minecraft where the block highlighting lines would render as broken triangles, other games are possibly affected as well
Vulkan: Optimized data uploads to GPU
On systems with unified memory (integrated GPUs) we will use cached shared memory which has very low overhead
Data uploads are generally not a bottleneck in Cemu but this optimization might still help with performance on low-end systems
OpenGL/Vulkan: Fixed a regression from 1.25.3 where textures would show incorrectly or garbled
UI: The graphic pack preset selection is now more robust and consistent
Previously it was possible that the active presets would differ from the ones shown as active in the UI
UI: Fixed an issue in the texture cache viewer window where the overwrite resolution column would not show the correct value
--1.25.3--
New in 1.25.3b:
Vulkan/OpenGL: Fixed graphic bugs introduced by one of the optimizations in 1.25.3
Vulkan: We had to disable multi-threaded pipeline loading for Nvidia GPUs due to driver crashes
The exact cause is still being investigated. We plan to reenable this feature for Nvidia GPUs once a solution has been found
New in 1.25.3:
Vulkan/OpenGL: Several smaller performance optimizations to decrease CPU load of the GPU emulation thread
Vulkan/OpenGL: Fixed performance regression introduced in 1.25.2
Vulkan: Pipeline cache loading is now multi-threaded and thus should be much faster
Vulkan: Fixed a severe memory leak during pipeline cache loading
GX2: Minor optimizations to various GX2 API functions
UI: Input window improvements
Slightly altered profile load/save buttons for better clarity. Making it easier to distinguish if a profile is created, updated or loaded
Show a warning if no GamePad has been configured as most games require one to be at least connected
logging: Cemu will now no longer overwrite the log file immediately on start. Instead it will only write it once a game has been launched or an error occurred
This is to prevent users from accidentally resetting log.txt merely by reopening Cemu
--1.25.2--
New in 1.25.1d
syshid: Various tweaks and fixes to the emulated HID driver (#545)
Fixes USB portal device randomly disconnecting in Skylanders Swap Force
Fixes high latency (up to half a minute) on some portal devices
Vulkan: Ignore invalid mips for MSAA textures
Fixes Snoopy's Grand Adventure (US) crashing on boot (#355)
The EU version still gets stuck at the language selection screen. A workaround for this is to use a save file with the language already set
Vulkan: Added support for little-endian encoded vertex indices
Fixes broken 3D geometry in Neko entertainment games (or anything that uses NGDK2 engine)
VPAD: Corrected behavior of touch-screen coordinates when in non-touching state
Fixes unclickable buttons in Neko entertainment games
AX: Implemented API AXSetVoiceOffsetsEx
F1 Racing should no longer crash on launch
UI: When launching Cemu with the -g option skip loading and displaying the game list
UI: More descriptive error messages when launching a game fails (e.g. due to moving game files but not updating the paths)
UI: Fixed an issue where changes to graphic packs settings would not save
nsysnet: Fixed a crash in getsockopt()
Seen in Skylanders Swap Force with online mode enabled
coreinit: Implemented API FSTruncateFile/FSTruncateFileAsync
Adventure of Pip will no longer freeze when saving
coreinit: Correctly handle the mirrored affinity bits in OSThread context
Fixes Othello softlocking on the titlescreen--1.25.1--
New in 1.25.1c
UI: Cemu will inform the user about the available Cemuhook update if an outdated Cemuhook installation is detected
New in 1.25.1b
general: A side effect of upgrading wxWidgets was that it broke compatibility with Cemuhook
This hotfix prevents outdated Cemuhook from crashing Cemu
You can get an updated version of Cemuhook for 1.25.1 on https://cemuhook.sshnuke.net/
New in 1.25.1:
general: We now ship with Cemuhook's shared fonts as the default system fonts
Our previous placeholder font was incomplete and lacked some special characters as well as many non-latin characters
Credits go to rajkosto for creating the fonts and hand-drawing the Nintendo specific glyphs
general: Fixed an issue where Cemu would create the mlc directory at the default location before the user set a location in the 'Getting started' window
general: Improved robustness of title/update installer. It should no longer crash when encountering unexpected errors
AX: Fixed behavior of AXGetVoiceLoopCount()
Resolves an issue where animations would reset or skip ahead in Splatoon and Super Mario Maker (#15)
This change may also positively affect games that are prone to random sound corruptions (e.g. Paper Mario Color Splash)
GX2: GX2ResetGPU() will no longer softlock Cemu
Games occasionally call this API if they believe the emulated GPU is stuck (e.g. due to excessive shader compilation stutter)
Seen in Xenoblade Chronicles X, Mario Tennis and Darksiders 2
UI: Removed precompiled shaders option from UI as it had no effect on Vulkan. There was also no reason to set it to anything but the default (auto) on OpenGL
This is just a UI change, none of the actual shader caching mechanics were changed
UI: Clicking the download graphic packs button in the 'Getting started' window will correctly open and show the graphic packs window
Previously the gfx pack window would either not open at all or show up empty
misc: Upgraded wxWidgets (GUI library) to version 3.1.5
This may resolve crashes that some users have been experience when accessing any file or folder selection dialog
--1.25.0--
New in 1.25.0b:
Vulkan: We further optimized pipeline caches to have a smaller file size
OpenGL/Vulkan: New shader cache format
50-70% smaller file size compared to the old format
Internally, it uses our modernized GPU state representation that we also use in the new pipeline cache files
Vulkan: Fixed a regression from 1.25.0 which could cause various random graphic bugs
New in 1.25.0:
Vulkan: Added a permanent cache for Vulkan pipelines
Unlike the Vulkan-native cache that Cemu used before, this cache does never reset
Additionally the new cache is independent of hardware and drivers and can therefore be transferred between different PCs
Technical info:
Pipeline caching works by capturing the state of the Wii U's GPU at the time of pipeline creation
During the pipeline loading screen Cemu can then play back those captured states to recreate the pipelines
Pipelines are directly tied to your shader cache. You need both caches to restore pipelines
Pipeline cache location: shaderCache/transferable/<titleId>_vkpipeline.bin (new)
Shader cache location: shaderCache/transferable/<titleId>_shaders.bin (new, updated with 1.25.0b)
Known issues:
The pipeline cache doesn't cover all edge cases yet and a very small fraction of pipelines can't be cached
It affects less than 0.1% of pipelines but we are looking to bring that number down to zero within the next 1-2 Cemu releases
coreinit: Fixed a recent regression which caused Pokken Tournament to crash or softlock on launch
general: Updated language files
--1.24.0--
New in 1.24.0b:
input: Minor internal tweaks to improve controller detection on SDL2
input: Fixed an issue where controller profiles could not be saved on a particular controller slot under very rare circumstances
New in 1.24.0:
input: Added SDL2 GamePad as a new input API (#514)
Offers native support for many controllers that would normally require external software (BetterJoy, DS4Windows, Steam)
Includes motion support for GamePad emulation (if motion data is provided by the controller)
SDL2 also acts as a wrapper for XInput, making it an convenient all-in-one solution
input: As part of introducing SDL2 we also reworked our motion handling (#329)
You should now have a much better experience using motion with both DSU but also the new SDL2 controllers
nlibcurl: Made server certificate checks more permissive to match new behavior in Wii U firmware 5.5.5
This fixes a bug where it was no longer possible to connect to Super Mario Maker course world

- The game list should now update after installing any title or update
New in 1.23.0b
general: Improved robustness of download manager and fixed a few bugs that could occur during the installation step
New in 1.23.0
general: It is now possible to download purchased Wii U eShop games, system titles and updates via our new Download Manager!
Like other online functionality, it requires dumped online files from a Wii U

Currently supported features:
- Downloading purchased eShop games and demos (owned games will be shared between your Wii U and Cemu)
- Buying games on eShop using the eShop Wii U application and downloading them via Cemu's interface. No game dumping required
- Downloading the latest updates for your owned titles
- Downloading some system titles (Friend list, eShop)
Note that DLC downloading is not yet supported but will be added very soon.
general: New FST reader (FST is the filesystem used for WUD, WUX and .app files)
Internal support for NUS content (.app) which ties into the Download Manager
Much higher read throughput than the previous implementation, may boost loading times on
lower end CPUs where FST processing sometimes became be a bottleneck
coreinit: Fixed thread cancelling not working correctly
This resolves an issue where browser based applications would softlock when trying to load any page
--1.22.13--
New in 1.22.13b
general: Fixed an issue where some installed DLC would not be detected
Vulkan: Fixed a rare crash that could happen randomly during gameplay
New in 1.22.13

- Emblems in Mario Kart 8 (#501)
- Character portaits in Hyrule Warriors (#174)
- Level preview images in Pokken Tournament
Vulkan: Added support for Latte GPU special state 5 (fast depth to color conversion)
Shadows in Tokyo Mirage Sessions #FE and Pokkén Tournament render correctly now
coreinit: Added API MEMDestroyFrmHeap
This resolves Color Splash crashing during some loading screens
coreinit: Further improved stability of TaskQueue API

This fixes a long standing issue where mirror effects in Level 1-5 would
cause the texture cache to be flooded, leading to stutter and sometimes even crashes if
not enough VRAM is available
coreinit: Optimized niche cases in Cafe OS synchronization primitives
This should improve performance in Paper Mario Color Splash when using multicore recompiler
The issue has not been entirely solved yet and further improvements are planned
Vulkan: Fixed a crash that could occur when a game supplied invalid texture sampler parameters
Resolves a crash in Super Meat Boy (#479)
GX2: Corrected a bug in the calculation of texture pitch for the tiling aperature
Fixes corrupted textures in Super Meat Boy (#479)

Required by some homebrew applications which mix OSScreen and GX2
coreinit: Implemented API MEMRecordStateForFrmHeap, MEMFreeByStateToFrmHeap
Used by WUT homebrew
--1.22.7--
general: The default vsync frequency (emulated refresh rate) is now 59.94 to match the actual console
Graphic packs can still set it to a flat 60
general: Fixed various small memory leaks
Vulkan: Revised internal swapchain management and fixed some synchronization bugs in the process
Double-buffered vsync should no longer cause graphical artifacts
Vulkan: Added a new experimental vsync mode
If enabled, Cemu will match the vblank event timing of the emulated display to the physical monitor on which Cemu is displayed
This reduces latency and avoids tearing by piggybacking on the emulated game's vsync implementation
For *perfect* results, the vsync rate in Cemu should be equal or slightly higher than the monitor refresh rate
As an example: When playing BotW on a 60 Hz monitor you want to set FPS++ to either 60 FPS or the next higher option. This is assuming stable 60 FPS can be maintained.
Alternatively, any integer ratio (1:2, 1:3, 1:4...) should give good results as well. E.g. 30 FPS on 60 Hz, 36/72 FPS on 144 Hz
Even for non-integer ratios (30 FPS on 144 Hz) this mode of vsync should perform at least as well as the Vulkan-native double buffered vsync mode
While this is only available for Vulkan right now, we plan on adding this to OpenGL in the near future
Vulkan: Cemu's internal shaders no longer show up in the overlay statistic ('Compiled x shaders'). Unlike game shaders they do not get cached and also do not cause any stutter
H264/DXVA2: Fixed incorrect handling of mismatching frame pitch
This should fix broken video playback in Mario Party 10 and Pikmin 3 on some GPUs
GX2: Fetch shaders with a size of zero won't cause a crash anymore (regression introduced with 1.22.6)
Resolves Minecraft crashing on launch
--1.22.6c--

The crash can most often be observed when loading saves in BotW but also can happen randomly during gameplay
coreinit: Avoid a race condition in thread deallocators
Fixes random crashes in various games
coreinit: Added a safeguard to prevent a state corruption when a game uses MPTaskQ improperly
Fixes Tokyo Mirage Sessions freezing or crashing shortly after launch (#472)
coreinit: Fixed a race condition in spinlock implementation
Improves stability of Tokyo Mirage Sessions and likely some other games
coreinit: Fixed OSScreenClearBufferEx() clearing a much larger data area than it should
This change should fix flickering and random crashes due to memory corruption in some homebrew titles
coreinit: Fixed an issue where the priority of default core threads was too high, leading to CPU starvation of other threads
Fixes random softlocks in Yoshi's Woolly World
GX2: Reworked GX2 event queue implementation to match behavior of actual console more closely
This resolves random softlocks in games that rely on GX2 events
GX2: Reworked fetch shader generation (GX2InitFetchShaderEx) to match behavior of actual console more closely
Improves compatibility with games that are picky about correct shader size. E.g. The Fall is now playable and no longer crashes on boot
Shader caches and graphic packs are not affected by this change
OpenGL/Vulkan: Fixed generation of invalid shader code when accessing integer texture samplers with certain parameters
Fixes an issue where the game screen was invisible in Virtual Console DS titles
