Cemu 1.7.1

Description

Cemu is a Highly experimental software to emulate Wii U applications on PC

 

  • Can run encrypted Wii U images (WUD) and RPX/RPL files
  • Internal resolution is 1920x1080 (if supported by game)
  • Contains basically no optimizations. Expect slow framerates and long load times.
  • Windows 7 or above (x64) (other platforms may be supported later)
  • Requires OpenGL 4.0
  • Tested on NVIDIA and AMD: Runs fine on most recent driver
  • Tested on Intel: Garbled output but runs if OpenGL version is supported

Changelog

Cemu detailed changelog for 1.7.1
Patreon release date: 2017-02-02
Public release date: 2017-02-09

 

  • General: Fixed a crashbug that could occur due to invalid syntax in graphic pack rules.txt

 

  • CPU/JIT: Threads can now continue execution inside recompiled code immediately after a context switch.
    Previously threads would default back to the interpreter for a short time
    As a result of this change performance in games with high amount of context switches is drastically improved
  • CPU/JIT: Fixed a bug in LSWI/STSWI instruction when nb = 2
  • CPU/JIT: Improved performance of SRAW instruction
  • CPU/JIT: Implemented conditional BL instructions
  • CPU/JIT: Improved handling for very large functions (PPC code size above 128KB)
  • CPU/JIT: Fixed a bug in the generated code for the MFTBL instruction
  • CPU/JIT:: Fixed a bug where the CR0 result was calculated incorrectly after AND instructions
  • CPU: Implemented ADDME instruction
  • CPU: Implemented OE versions of MULLW, ADD and NEG instruction in interpreter

 

  • Coreinit: Fixed a bug in BlockHeap block allocation that eventually could lead to memory corruption
  • Coreinit: Implemented FS working directory support
  • Coreinit: New API: IMGetTimeBeforeDimming(), OSSetAlarm(), FSChangeDir()
  • Coreinit: Fixed incorrect size alignment in DCZeroRange()

 

  • Input: Fixed a bug that caused slowdowns due to inactive controllers

 

  • VPAD: Changed internal raw touch coordinate bias and scale to match a real Wii U GamePad

 

  • RPL: Better TLS support
  • RPL: Added support for relocation types 251 and 253

 

  • H264: New API H264DECSetParam_OUTPUT_PER_FRAME()

 

  • AX: Fixed voice loop counter not correctly incrementing for PCM16 or PCM8 voices

 

  • GX2: Reverted change from 1.6.3, R10_G10_B10_A2_SNORM GX2 format is represented using GL_RGBA16_SNORM again
  • GX2: Fixed a graphic pack related crash bug that could occur due to upscaled depth textures
  • GX2: Fixed a bug that caused textures to be overwritten with outdated data after a clear operation
  • GX2: BC4 textures now correctly duplicate the color to all channels instead of just the red channel
  • GX2: Cemu will now free unused textures to conserve VRAM
