1.4.1 is live for Patreon supporters

# CEMU detailed changelog for 1.4.1
# Patreon release date: 2016-04-07

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

I can 100 % verify this. Mario kart 8 runs amazing in time trails, and while normal races have slowdown, it is still very playable! With this new version, super mario 3d world now also runs basically full speed. It's incredible really. Outside of some weird shadow artifacts, the game is now basically fully playable or me! The emulator does seem to have some "warm up" period on my rig, it stutters like crazy for like 10-15 minutes after starting a game, but when that is over, it flies! I am incredibly impressed.

My rig:

i7 870 @ 3,3 ghz
GTX 970
8 GB RAM
Windows 10 64-bit

I wonder how bad/good some of these games would run on my PC (i7 2660 /r7 260x). I could try them myself but I don't know how to dump digital Wii U games :p

It's incredible how a system like the WiiU (which should be slightly more powerful than a 360) runs as good on current CPUs. I was always under the impression that a current PC can only emulate systems that are at least 2 generations behind (in terms of processing power).

For instance, current "next gen emulators" that run perfectly are PS2, GC and Wii (which is basically the same as the GC). For 360/PS3 i assumed we will have to wait for CPUs that will be released in the next 2 or 3 years at least. And yet the WiiU seems like it's going to run fine on current CPUs... heck some of that footage is taken using some that are several years old already.

"Generation" labels have nothing to do with ease of emulation. Generations are simply measures of time.

Ease of emulation is a complex subject and has a lot of factors that play into it. The way that consoles have moved towards running games in more abstracted environments is probably helping things along with modern systems, since it means games are less reliant on a super accurate imitation of the hardware.

Well, we thought 360 emulation was impossible, and Microsoft pulled it off on a laptop processor.

Also, CEMU doesn't have wide compatibility and I don't know how many hacks the programmer is using. It doesn't even run on recent AMD drivers.

Well, it's not even out half a year and still has an amazing pace. Did they cut corners? Perhaps but this is one of the fastest progressing emulator ever and already has amazing speed and good compatibility for its age.

I mean I'm not dogging on the guy - great work - but there's a difference between true accurate emulation and basically quasi-porting individual games to x86 (which is pretty much what ZSNES and it's ilk were doing).

An actual accurate Wii U emulator at native speed is probably a decade or more off. An emulator that targets popular games but has to basically do a lot of customization per game to get there will have big gains at first but will slow down once the major interests are compatible.

I'm not too sure about this; atleast the authors claimed that a "no hacks" approach was one reasoning as to why the are keeping it closed source. Way back before the patreon etc

Well, I finished many, many games when I used ZSNES 16 years ago. Was it an accurate emulation? Of course not. But could you see it? Not that often.
Also do you think Dolphin is more accurate?
I mean, yes, cycle accurate emulation is of course far off but does it need to be accurate? And why?

Changelog up. They also announced earlier on Patreon they had a new non-serial based security system. Have to imagine it calls home at this point.

# CEMU detailed changelog for 1.4.2
# Patreon release date: 2016-04-30

general: FPS counter now updates more frequently

CPU: Improved recompiler code generated for DCBZ instruction.

h264: Simulate successful video decoding rather than returning errors (proper video decoding is still WIP. The new workaround fixes freezes where the game was waiting for video playback to happen)

coreinit: Fixed a bug in OSReadRegister16() and OSReadRegister32Ex() where 0 was returned instead of the actual register value
coreinit: Added weak-symbol __gh_FOPEN_MAX
coreinit: Added API OSWakeupThread()

ax: Added support for AUX bus callbacks (New API: AXRegisterAuxCallback)
ax: Added support for voice protection (New API: AXVoiceBegin, AXVoiceEnd, AXVoiceIsProtected)

GX2: Added permanent shader cache
Everytime a previously unknown shader is loaded, the shader and all releated renderstate information cached in a file.
When CEMU boots a game, it will use the cached information to reconstruct all known shaders right away.
This significantly can decrease stuttering during emulation but it will also increase boot times.
GX2: Added support for GX2WaitTimeStamp()
GX2: Added support for swap interval configuration via GX2SetSwapInterval()
GX2: Added support for binding depth textures as color targets
GX2: Fixed a bug where color or depth buffers were not correctly cleared.
GX2: Support for texture depth compare modes 'never' and 'always'.
GX2: Reworked texture loader code

FS: Added API FSGetMountSource()

vpad: Added VPADGetTPCalibratedPointEx()
vpad: VPADGetTPCalibratedPoint() now correctly copies the touch flags
Click to expand...

Wasn't expecting them to implement a permanent cached shader feature, though it's a nice stop gap. Isn't this basically what the Ishiiruka ver of Dolphin does?

edit: 1.4.2 up on Patreon now

Dolphin uses a shader cache. I think you might be mixing that up with the async shader compilation.

Cemu 1.4.2 game updates:

- Bayonetta
- Hyrule Warriors
- The Legend of Zelda: Twilight Princess HD
- The Legend of Zelda: The Wind Waker HD
- Mario Kart 8
- One Piece: Unlimited World Red
- Super Mario 3D World

Ah, I figured the Dolphin shader cache was regenerated every time it's run and not saved permanently. I get the distinction with async and the emulator not waiting for them to generate.

How is multicore handled on the emulator these days, I'm seeing a lot of people's specs where overall frequency being higher seems to be the say to go, is this down to just performance in general or does the emulator favir maximum clock frequency over corecount?

Heads up for controls: if you switch to another controller type, your previous type's bindings aren't saved so make sure to export them first.

Looks like Bayo 2 and Star Fox Guard are still broken in 1.5.1 ]:

WTF? These are running in real time? How the hell did this emulator evolved so quickly?
Absurd, amazing well done stuff. This is basically playable now. Some small fixes in the lighting and MK8 / 3D World will be basically perfect.

Not about Cemu but the open source Wii U emulator Decaf is apparently now capable of rendering the Mario Kart 8 title screen:

It would be nice if Decaf gets to the point of being a legitimate contender for Wii U emulation. A closed source only future for Wii U emulation would kind of suck.

I'm not sure what was even the point of implementing mip-mapping, to be honest. All it does it make the textures look blurry.
Click to expand...

I think this may be one of those things that shows off MUCH better in motion than in screenshots.

The non-mipmapped textures on the left handside would be showing OBSCENE amounts of aliasing (shimmering) because it's trying to fit all of the detail in such a small space. Mipmapping uses lower resolution versions depending on how small the area the texture being applied to is.

It looks blurry in the screenshot but it looks like theres one other piece missing that would ideally make it look as great as it can, which is anisotropic filtering.

Yeah, anisotropic filtering is pretty much needed for the mip mapping to actually look good. But without it, mip mapping just makes things look worse, IMO.

Only just realized with these previews that games that natively run 1080p, output at that resolution when in fullscreen as opposed to always 720p in windowed. Guess it's not much of a factor since Smash and TPHD are some of the few games that run that res.

1.5.2 up for Patreon

# CEMU detailed changelog for 1.5.2
# Patreon release date: 2016-06-09

coreinit: Improved performance of ExpHeap memory library.

AX: Added sndcore2 API AXAcquireVoice, AXAcquireVoiceEx, AXFreeVoice, AXVoiceBegin,
AXVoiceEnd, AXSetVoiceVe, AXSetVoiceOffsets, AXSetVoiceType,
AXSetVoiceDeviceMix, AXSetVoiceState, AXSetVoiceSrc, AXSetVoiceSrcRatio,
AXIsVoiceRunning, AXGetVoiceOffsets

Input: Fixed a bug where mapping any keyboard button would always set the key to "0xFF"

GX2: Added support for cubemap array textures
GX2: Added support for mip-mapping (all texture types)
GX2: Better handling for textures with a width or height that is not a multiple of 4
GX2: Fixed a bug in Tiling Aperature where texture pitch (width) was calculated incorrectly
GX2: New API GX2InitSamplerZMFilter(), GX2InitSamplerLOD(), GX2InitPolygonControlReg(), GX2InitPolygonOffsetReg()
GX2: Improved streamout shader emulation performance
GX2: Implemented support for directly rendering into the scanbuffer
GX2: Texture format R10_G10_B10_A2_SNORM now uses GL RGBA16_SNORM representation (since there is no signed version of RGB10_A2 in OpenGL)
GX2: New debug option 'Overwrite vertex buffer size'.
With this option enabled, CEMU will calculate the size of vertex attribute data that needs to be uploaded to the GPU instead of relying on the value provided by the game.
Can boost performance but may also make the vertex cache less efficient.
