Cemu Plus 0.4.0

Android build of Cemu Plus, a fork of the Cemu Android port with Lossless Scaling frame generation.

What's new

Motion sensitivity

• Motion sensitivity X axis and Motion sensitivity Y axis set how fast turning left and right, and tilting up and down go, from 25% to 500%. They are next to the motion inversion on each controller's page in Input settings and in the quick menu under Controls, and work for the motion of the device and of controllers
• They scale the turning speed the game gets, which is what aiming with motion uses. A tilt that is held still settles at the real angle of the device

Updated to the latest Cemu

Cemu Plus now includes everything the main Cemu project added since April 2026:

• Wii U CPU on ARM: fixes in the ARM64 recompiler that runs every game, for single-precision float stores (now faster too), division by zero, carry flags and a few wrong instructions. The default NaN mode of ARM is turned off to match the Wii U
• Performance: smaller Vulkan and GPU optimizations, like checking only the render state that changed, caching shader lookups and using the fast draw path more often
• Rendering: better texture readback (e.g. Color Splash and Xenoblade Chronicles X), textures are refreshed when a game invalidates their memory, mip and slice handling, offsets of some texture sampling modes and many shader corrections
• Videos: the colors of in-game videos are right on ARM devices, and video decoding handles interrupted streams better
• Audio: more accurate sound mixing and sampling
• Compatibility: more Wii U system functions, like the dynamic library notifications, alarm queues, exit() and date conversions, and more of the software keyboard
• Stability: more state is reset when a game closes, so starting another game afterwards is more reliable, and fixes for crashes when a game exits or the app closes while a game boots
• Online: reworked network code
• Graphic packs: patches load faster and their code caves get the full size

Fixes

• Games that point a texture at memory that doesn't exist no longer crash the emulator. The texture is cleared instead. Sonic Lost World crashed this way when Start was pressed on the title screen
• Games in a folder picked with the file picker are read more reliably. After one failed read, every later read of that file came back empty

Logs

• The emulator log is also written to logcat, so it can be read with adb while a game runs

Frame generation setup

1. Copy Lossless.dll from your own copy of Lossless Scaling (its installation folder on Windows) to your device.
2. In Cemu Plus open Settings → Graphics settings → Frame generation (Lossless Scaling) and tap Select Lossless.dll.
3. Enable frame generation there or from the in-game menu, where the multiplier, target frame rate and motion estimation resolution can be changed while playing.

Frame generation requires the Vulkan memory model, float16 and null descriptor support from the GPU driver.
The FPS overlay shows the displayed frame rate together with the base frame rate while frame generation is active.

Cemu Plus 0.3.6

Android build of Cemu Plus, a fork of the Cemu Android port with Lossless Scaling frame generation.

What's new

Input settings, redone

• Each controller has all its settings on one page, the ones used most first: what it emulates, the controller in use with Set up all inputs, its buttons and sticks, motion, rumble, profiles, and the stick and trigger sensitivity at the end under Advanced. The Controller settings dialog and the separate Device settings screen are gone
• The controller in use is picked from the connected ones right on the page, and Set up all inputs binds that one directly
• Invert motion X axis and Invert motion Y axis are next to Use motion on each controller's page
• The touch screen, sensors and vibration of the device can be moved to a controller from its page, and the vibration strength of the device is set there too
• The inputs are shown as a grid of tiles that say Not set when nothing is bound
• The input settings list the controllers in use, with Add a controller for the next free one, then Hotkeys and On-screen controls

Controller profiles per game

• A controller can be saved as a named profile, and loaded or deleted again, from its page
• The game settings start with a new Controls section. Each controller uses your global controls until you tap Customize for this game, which gives the game its own copy of them and opens it to change. Edit controls opens it again later and Use global controls goes back. Profiles saved in the input settings can be picked there too. Changes made while that game runs are saved to its controls
• The game settings show the most used settings first: Controls, GamePad screen crop and Graphics, with Thread quantum last under Advanced

Wii U style settings

• Every settings screen has the white and silver look of the Wii U settings, with panels, round switches and a cyan highlight, like the game settings on the second screen
• The settings home has an icon for each section
• Overlay settings are now Toolbar settings, the name used everywhere else

Sliders with a gamepad

• Up and down on the D-pad move past a slider to the next setting instead of changing it
• Press A on a slider to change it with left and right, A again keeps the value and B puts the old one back. Left and right also change it right away

Game library with a controller

• A guide in the corner of the library shows what the buttons do once a controller is used: A starts the game, Y opens its game settings, X the settings of Cemu and Start its options. It works in the grid and in the list
• With the second screen on, Y moves the controller to the game settings shown there, so they can be changed without touching the screen. B goes back to the games
• In the list, the second screen shows the game the controller is on, not only the one that was tapped

Motion controls

• Invert motion X axis and Invert motion Y axis flip turning left and right, and tilting up and down. They work for the motion of the device and of controllers, and can be found in Input settings and in the quick menu under Controls

Quick menu

• A new Input section opens the input settings, or the settings of each controller in use, without leaving the game

Fixes

• Star Fox Zero no longer crashes when shots hit the ships in the tutorial. The game uses 64-bit values that the emulator handled with ARM64 instructions that need a stricter memory alignment than the Wii U does

Crash reports

• Share log file and Open Cemu folder use the data folder Cemu is using. With a custom data folder they showed the default folder, so the shared log could be from an old session
• When the emulator crashes, the crash details (signal, native backtrace, the game and the Wii U CPU state) are written to log.txt before the app closes, and to logcat. Before, the app could close before they were written
• Android also writes its own crash report (tombstone) for emulator crashes now

Frame generation setup

1. Copy Lossless.dll from your own copy of Lossless Scaling (its installation folder on Windows) to your device.
2. In Cemu Plus open Settings → Graphics settings → Frame generation (Lossless Scaling) and tap Select Lossless.dll.
3. Enable frame generation there or from the in-game menu, where the multiplier, target frame rate and motion estimation resolution can be changed while playing.

Frame generation requires the Vulkan memory model, float16 and null descriptor support from the GPU driver.
The FPS overlay shows the displayed frame rate together with the base frame rate while frame generation is active.

What's new

Fixes

• With Swap screens on, a game starts with the GamePad image on its screen. Before, both screens showed the TV image until Swap screens was turned off and on again
• Swapping the screens keeps the toolbar where you put it. It moved to the top when the GamePad image was centered on its screen

GamePad screen crop

• The crop is off for every game until it is turned on in that game's settings. Before, the switch showed as on for all games even when nothing was cropped
• The game settings and the quick menu say when Swap screens is on, because the crop is only used while the GamePad is on the second screen

What's new

Game settings on the second screen

• With the second screen in use, picking a game in the library shows its settings on the second screen, where they can be changed with touch. Tap a game once to pick it and again to start it, or tap Start on the second screen. With a controller, the game the cursor is on is shown and A starts it
• The game settings (Edit game profile) are redone in the style of the Wii U Menu: the game's icon with its play time, last played date, region and version, switches on white panels and one tap choices for CPU mode, thread quantum and custom driver
• The GamePad screen crop section has the same look
• The game settings start with the ones used most: GamePad screen crop first, then the custom driver under Graphics, and the CPU, shader and library settings last under Advanced

Fixes

• The app opens faster. Graphic packs were loaded twice at startup, and with a custom data folder every save was synced with it before the app could show anything. That sync now runs in the background, and games wait for it before they start
• Exiting a game no longer hangs the app. The way the app closed could get stuck while the emulator was still running, and with a custom data folder all saves were copied again on the main thread. Now only the saves that changed are copied, in the background
• Shader caches are written to storage right away, so closing a game does not lose them

What's new

Swap screens

• Swap screens in the setup wizard and in Screen layout, for devices where the second screen is found the other way around, like the Dual Screen add-on of the Retroid Pocket Mini. It puts the GamePad on the main screen and the TV image on the second screen
• While setting up the screens, the setup wizard shows on the second screen itself whether it gets the TV or the GamePad image, so it is easy to see if swapping is needed
• The choice is remembered, including when it is changed from the quick menu
• Fix: the toolbar buttons work with swapped screens when the toolbar fills the black bar

Toolbar

• The toolbar goes with the GamePad image by default, so swapping the screens moves it along. Toolbar goes on in the setup wizard and in Screen layout puts it on the TV screen instead
• The setup wizard's toolbar step shows the layout preview on the second screen itself, with the toolbar and the game image, to judge it on the real screen and its shape
• The setup wizard and the settings say when the black bars are too thin for the toolbar, so it floats over the game, and how to minimize it

Toolbar over the game

• When the toolbar is drawn over the game instead of in a black bar, it has a hide key in its top right corner
• A hidden toolbar becomes a small bubble with the frame rate. Tap the bubble to bring the toolbar back. The choice is remembered
• Minimized toolbar position picks the corner of the bubble: top left, top, top right, bottom left, bottom or bottom right

Controls

• The Android back button opens the quick menu with one press during the game, also the back button of handhelds with built-in controls

Frame generation setup

1. Copy Lossless.dll from your own copy of Lossless Scaling (its installation folder on Windows) to your device.
2. In Cemu Plus open Settings → Graphics settings → Frame generation (Lossless Scaling) and tap Select Lossless.dll.
3. Enable frame generation there or from the in-game menu, where the multiplier, target frame rate and motion estimation resolution can be changed while playing.
