Cemu 1.11.1 Now Out For Patreon Supporters; New Video Shows Zelda Breath Of The Wild Current Performance


A new version of Cemu, the Wii U emulator allowing PC players to enjoy Nintendo exclusive titles like Super Smash Bros for Wii U and Zelda Breath of the Wild, has been released recently.

The new version of the emulator, which is currently available only to those who are supporting the developers on Patreon, introduces several improvements such as better online support and more. Check out the full update notes below.

Wii U PC Emulator CEMU 1.19.0 Adds Experimental Option to Reduce Stutter by Sacrificing Emulation Accuracy; Releases Publically This Week

general: Improved online support, as a consequence Cemu now requires all ccert and scert files to be dumped
general: Input window should open faster
general: Improved error description when file copy operations fail (save migration and update/DLC installer)
general: Cemu will generate meta folder for saves if not already present (necessary to identify saves)
general: Updated application and window icon
general: Updated game profiles
PPC/JIT: New global linear-scan register allocator
Previous register allocator would only look at blocks of uninterrupted instructions, while the new RA can allocate registers across branches and loops, resulting in code with far less memory read/writes. If you know x64/ppc asm and want to see an example, check this link: http://cemu.info/changelog/cemu1.11.1_ra.txt
PPC/JIT: Use BMI2 SHRX/SHLX for PPC SRW/SLW (if supported)
PPC/JIT: Detect and replace common ADDIC+SUBFE pattern with x64 optimized code
coreinit: Added missing MEMCreateUnitHeapEx, MEMDestroyUnitHeap exports
coreinit: Fixed bugs in memory heap implementations
coreinit: Added API MEMGetNthListObject, MEMGetPrevListObject, MEMPrependList, MCP_GetSystemVersion, MCP_TitleListByDevice
ax: Small tweaks and optimizations to audio handling
nn_ac: Added API GetConnectResult, GetLastErrorCode, GetStatus
nn_ac: Fixed the return values of IsApplicationConnected, GetConnectStatus, GetAssignedAddress, GetAssignedSubnet
nn_act: Implemented API AcquireIndependentServiceToken
nn_acp: Implemented API ACPGetSaveDataTitleIdList, ACPGetTitleSaveMetaXml, ACPGetTitleSaveDirEx
nn_erreula: Implemented preliminary support for nn_erreula library
nlibcurl: Implemented a large chunk of Cafe OS nlibcurl functions
GX2: Fixed a bug that caused a mismatch between geometry and pixel shader attribute location
GX2: Fixed a rare bug that caused textures to be dropped from the texture cache after a period of time despite being still in use
nsysnet: Added API NSSLCreateContext, NSSLSetClientPKI, NSSLAddServerPKI, NSSLAddServerPKIGroups, NSSLDestroyContext

As usual, most are curious if there have been performance improvements for Zelda Breath of the Wild. A new video shared by YamGaming shows the performance that can be obtained with a machine powered by an i7 6700k @ 4.5ghz CPU, GTX 1070 GPU and 16 GB RAM.

Cemu 1.11.1 is now available for Patreon supporters. It will be made available to the public on November 27th.
