Créé par Exzap, il s’agit du second émulateur de Wii U à être disponible au public mais le premier à pousser jusqu’à l’émulation de jeux commerciaux. Il peut décrypter les images Wii U qui utilisent le format Wud mais également les fichiers RPS ou RPL. La résolution interne peu aller jusqu’à 1920×1080 selon les jeux. A noter que pour le moment, un seul contrôleur est accepté, il s’agit du DRC (GamePad) de la Nintendo Wii U. Cette version n’est compatible que pour les Windows x64 (à partir de Windows 7) avec une carte graphique gérant OpenGL 4.1 ou supérieur et il faudra posséder 4 à 8 Go de mémoire vive (Ram) pour le faire fonctionner. (Correspondance ID-Titre).

Les changements:
En résumé:
– Added support for native online play
– Overhauled account and save handling
– Graphic and input fixes
– Improved compatibility
– Tons of bug fixes and smaller tweaks
En détails:
# New in 1.11.0c:
– coreinit: Fixed a rare memory corruption bug that caused FSOpenFileAsync() to fail on valid files
# New in 1.11.0b:
– general: Fixed a bug that made it impossible to enable online mode
– coreinit: Fixed a problem where save files would sometimes not be detected by a game
# New in 1.11.0:
– general: Added support for native online play for games that use NEX (requires otp, seeprom, account data and certificates dumped from a Wii U)
– general: Updated game profiles
– general: Added « streamoutBufferCacheSize » game profile option
– general: Added « extendedTextureReadback » option (fixes Pikmin 3 and possibly other games, credits and thanks @ epigramx for the finding)
– general: Added « threadQuantum » game profile option to control amount of virtual PPC cycles executed per thread time slice
– general: Updates and dlcs can be now installed (but not downloaded) more conveniently via Cemu’s UI. File -> Install game update or DLC -> select the meta.xml in the meta folder of the update
– general: Added logging option for socket API
– PPC/Interpreter: Fixed a bug in PSQ_L* instruction that caused the second value to be extended with the incorrect sign bit
– PPC/Interpreter: Minor optimizations in PSQ_L* instructions
– PPC/Interpreter: Added instruction PS_CMPU0
– PPC/JIT: Move instructions that affect CR closer to conditional jumps so we can cache CR in x64 flags register (optimization for loops and branch heavy functions)
– coreinit: Rewritten ExpHeap, MBlock MEMList, SpinLock code
– coreinit: Rewrote MEMInitBlockHeap, MEMCreateFrmHeapEx, MEMCreateUnitHeapEx to match the new internal memory structures
– coreinit: Added API MEMDestroyUnitHeap, MEMDestroyBlockHeap, IOS_Ioctlv, OSUninterruptibleSpinLock_Acquire,
OSUninterruptibleSpinLock_Release, OSUninterruptibleSpinLock_TryAcquire, OSUninterruptibleSpinLock_TryAcquireWithTimeout,
IM_GetParameter, IMGetAPDPeriod
– input: Deadzone is normalized correctly now and should be the same for xinput and directinput devices
– input: Fixed calibrating for certain directinput devices
– input: Fixed a bug that caused controllers not to appear in the device list after click the refresh button
– nn_save: New save library implementation
Using the correct save path: /mlc01/usr/save/… (instead of /mlc01/emulatorSave/..)
Cemu will automatically migrate old saves to the new location (if user confirms a message box)
Create meta files that identify a save (iconTex.tga, meta.xml, saveinfo.xml)
The new implementation also covers more nn_save API
– nn_acp: Added API ACPUpdateSaveTimeStamp, ACPCheckApplicationDeviceEmulation, GetUtcOffset, GetUtcOffsetEx
– nn_boss: Added support for reading BOSS storage (mlc/usr/boss/)
– nn_sysnet: Added API mw_socket, shutdown, inet_pton, recvfrom_ex, sendto, sendto_multi
– Iosu: Implemented crypto and account modules
– zLib: Added API deflateInit2_, deflateBound, deflate, deflateEnd
– GX2: Added support for data-merging of BC3 and BC4 textures with matching integer formats
– GX2: If supported, use AVX2 to decode 16bit indices
– GX2: Optimized tiling aperature
– GX2: Fixed a bug where the pixel shader decompiler would ignore the current state of geometry shader outputs and instead use the outputs of the vertex stage
– GX2: Various smaller optimizations
– AX: Fixed crash caused by buffer overflow when the samplerate ratio of a voice was very low
– AX: Fixed a crash bug in biquad filter
– AX: Added API AXGetAuxCallback
A noter que des packs graphiques haute définition sont disponibles ici. Ils permettent, entre autre, d’augmenter la résolution native des jeux car contrairement à Dolphin et parce que la machine est techniquement différente il n’est pas possible à Cemu d’augmenter la définition autrement que par cette méthode.
A l’inverse, des packs SD (définitions standards et/ou basses) sont disponibles sur ce lien et permettent à certains PC manquant de performance de lancer des jeux en 60 FPS.
