cemu 1.7.3 released

cemu has finally released its highly anticipated 1.7.3 version of cemu, in this version we finally saw the newly launched latest zelda breath of the wild work.

# New in public release:

general: New game profiles

# New in 1.7.3d:

GX2: 1.7.3 accidentally broke compatibility with pre-1.7.3 cached shaders. This hotfix restores backward compatibility.
Also made some adjustments to guarantee this doesn't happen again in the future.

# New in 1.7.3b/c:

JIT: Fixed potential softlock for busy-wait loops which use the LWARX/STWCX instructions
GX2: Fixed incorrect shader source generated for streamout write exports when the shader is optimized for float-only

# New in 1.7.3:

JIT: LWARX instruction now consumes multiple virtual cycles. This speeds up busy wait loops.

general: Screensaver/Standby should no longer come up while a game is playing in Cemu

coreinit: Added API LCDisableDMA(), LCGetAllocatableSize(), MPResetTaskQ(), OSPeekMessage(), OSEnableHomeButtonMenu()
coreinit: Fixed bug in LCEnableDMA()
coreinit/FS: FSOpenFile() is no longer blocking CPU execution
coreinit/FS: Added internal support for priority-based path overloading
coreinit/FS: Cemu will load patched game files automatically from mlc01/usr/title/../../

ACP: Added ACP library. New API: ACPCheckApplicationDeviceEmulation()

AOC: Added proper support for AOC library. Addon content (DLC) is automatically loaded from mlc01/usr/title/../../aoc/ or mlc01/usr/title/../..//

AX: Fixed internal ADPCM playback offset calculation for addresses above 0x80000000

Input: Fixed bug that caused non-keyboard buttons to be detected as keyboard input

GX2: Improved implementation for GX2CalcTVSize() and GX2CalcDRCSize()
GX2: Shader code optimizations. Up to 40% faster compile time for float-only shaders (measured on NVIDIA)
GX2: Added support for shader OP3 CNDGT_INT instruction
GX2: Added support for vertex format FMT_16_16_16_16, nfa=0, signed=0
GX2: Fixed software streamout reading format 32_32_32_FLOAT incorrectly
GX2: Added support for vertex shader gl_PointSize export
GX2: Fixed a race condition in which the GPU7 command processor could run ahead of the current write pointer before GX2Init() was called
GX2: Fixed sampler min and mag filter value being read from wrong register bits
GX2: Added support for streamout binding the same buffer as input and output

cemu 1.7.2

A new version of cemu released today, now at 1.7.2
Heres whats changed:

# Cemu detailed changelog for 1.7.2c
# Patreon release date: 2017-02-16
# Public release date: 2017-02-23

# New in 1.7.2c:

GX2: Fixed a bug in GX2SwapScanBuffers() that could cause the GPU command stream to get corrupted

cemu 1.4.1 released

A new version of cemu released today, now to version 1.4.1

From the change log:

CPU: Added new instructions to recompiler: LWARX, STWCX, STWBRX, LHAUX, LHZUX, type 5, 6 & 7 for PSQ_L and type 5, 6 & 7 for PSQ_ST, DCBZ, ADDC, MFCR, FDIV, FADD, PS_SUB, PS_NEG.
CPU: Improved handling of XMM registers in recompiler. Drastically reducing the number of load/store operations when not enough registers are available.
CPU: Added SUBFME to interpreter.

coreinit: New API __ghs_mtx_init(), __ghs_mtx_dst(), __ghs_mtx_lock(), __ghs_mtx_unlock(), OSSleepThread()
coreinit: Added weak-symbol 'environ'

RPL: Added support for SDA and SDA2

fsa: Asynchronous file operations now support sending the result via message queue (instead of callback)

GX2: Added vertex data cache (cache vertex data in GPU memory instead of re-uploading it for every drawcall)
GX2: Fixed texture decoding for compressed textures with a size smaller than 16x16
GX2: Fixed AMD issue that occurred when glDrawBuffers() enables unused color attachment
GX2: Fixed AMD issue that occurred when glPrimitiveRestartIndexNV is used instead of glPrimitiveRestartIndex
GX2: Fixed AMD driver crash that could happen after shader compilation.
GX2: Fixed a multitude of issues when using Intel GPUs. Graphics are still horribly broken due to Intel's lacking OpenGL driver, but at least we can say we tried our best :)
GX2: Invalidate destination texture in cache after GX2SurfaceCopy()

vpad: Clamp left and right stick to length 1.0

### New in public release ###

general: CEMU now displays which GPU is used in the titlebar.

GX2: Fixed a timing related bug that could cause the emulator to stop rendering frames.

cemu 1.3.3 released

New version of cemu released now 1.3.3
Changelog from the website

--- New in public build ---

GX2: Fixed a bug where textures were sometimes wrongly decoded due to invalid bank/pipe swizzle values.

--- Changelog of Patreon build ---

general: Can now hold TAB to show GamePad screen (Note: We will add customizable methods to display the GamePad screen in a future release)

swkbd: Added preliminary support for Software Keyboard (only alphanumeric input is allowed for now, unicode support is still being worked on)

coreinit: Added implementation for some functions of the block heap API
(New API: MEMInitBlockHeap, MEMAddBlockHeapTracking, MEMGetTrackingLeftInBlockHeap, MEMAllocFromBlockHeapEx)
coreinit: Fixed a bug where PPC thread priority would sometimes not update correctly

save: Fixed a crash that could happen in SAVEOpenDir()

vpad: Improved implementation of VPADRead() fixing an issue where games incorrectly detected touch on/off.
vpad: Fixed touch offset calculation in fullscreen mode

GX2: Added initial support for Streamout
Streamout is also known as 'Transform Feedback' in OpenGL.
This is a rather complex feature and our implementation is far from complete. More improvements to Streamout will come in later CEMU releases.
In order to correctly replicate the low latency between CPU<->GPU enabled by the unified memory model of the Wii U we have to emulate Streamout shaders on the CPU rather
than using OpenGL's transform feedback. Despite this we expect that there is no performance penalty.
GX2: Implemented GX2RCreateSurface API
GX2: Proper support for texture format R32_G32_B32_A32_FLOAT and R32_G32_B32_A32_UINT
GX2: Fixed a crash in GX2CopySurface which could occur when the caller supplied a wrong surface->pitch value.
GX2: GX2CopySurface can now copy dynamically created textures that only reside in the GPU texture cache.

    Wednesday, October 14, 2015


I present to you Cemu. World's first Wii U emulator capable of running and rendering commercial games!

Quick facts:

Can run encrypted Wii U images (WUD) and RPX/RPL files
Internal resolution is 1920x1080 (if supported by game)
For controller input see Here.

Contains basically no optimizations. Expect slow framerates and long load times.
Windows 7 or above (x64) (other platforms may be supported later)
Requires OpenGL 3.3
Tested on NVIDIA: Runs fine on most recent driver
Tested on Intel: Garbled output but runs if OpenGL version is supported
Untested on AMD

Version 1.0.0 (Win x64)

Can the controller be configured?
Not yet, it's locked to using the GamePad via keyboard. Proper controller support will come in a future release.

Can I run extracted games?
No, when launching a Wii U executable directly (.rpx) no external files are supported. If you want to run a game, it needs to be in raw dump format (WUD or ISO).

Is there supposed to be sound?
No, audio is not yet supported.

What's next?
The current plan is to release new updates at least every two weeks. A more detailed roadmap is in the works.
