Cemu detailed changelog for 1.8.2b
Patreon release date: 2017-07-18
Public release date: 2017-07-25
New in 1.8.2b:
- CPU/JIT: Fixed crash that could occur during instruction analysis
- misc: Added some exports for Cemuhook
New in 1.8.2:
- general: Any .rpl files placed in cafeLibs/ directory will be loaded instead of the internal HLE modules (experimental feature, no real use yet)
- general: Cemu window can now be resized
- CPU/JIT: Fixed a bug in recompiler SRWI instruction
- CPU/JIT: Fixed a bug that could cause the recompiled code to skip an instruction if the thread was switched between the beginning of a loop and an inlined function
- CPU/JIT: Added STBUX instruction to recompiler
- CPU/JIT: Several other optimizations for the recompiler:
- Use AVX non-destructive 3-operand instructions to optimize some copy operations away
- Delay/Avoid endian-swapping between LWZ/STW if the data is not used for any other operation
- Generate shorter code for BCTRL, BL, BLR and other far branches (2 instructions, only 1 for far branches with no LR update)
- Replace branches with conditional moves (CMOVcc) if possible
- Avoid redundant FPR loads and stores
- Better detection for situations where x64 flags can be used instead of testing CR bits
- Avoid extra work of thread scheduling checks in tight non-infinite loops
- coreinit: New API OSTryAcquireSpinLockWithTimeout(), OSSwitchFiberEx(), MCP_Open(), MCP_Close()
- coreinit: More accurate emulation of foreground bucket memory and it's subregions
- coreinit: FSOpenDir() no longer ignores the current working directory
- coreinit: Fixed integer overflow in OSTicksToCalendarTime()
- AX: Added AX voice debugger
- AX: Fixed biquad filter
- AX: New API AXSetVoiceSamplesAddr(), AXSetVoiceLoopOffset()
- GX2: Improved detection of changed data for typical screen-size textures in texture cache (fixes softdec videos)
- GX2: Fixed invalid GLSL code being generated for 3D texture access with offset
- GX2: Fixed bug in indices generation for PRIMITIVE_RECTS
- GX2: Fixed a bug where adding entries to a shader cache .bin archive would sometimes have no effect (causing
- Cemu to recompile the affected shaders everytime)
- GX2: Various smaller optimizations throughout the graphic backend (performance gain 1-3%)
- GX2: Added support for tileMode filter in graphic packs texture rules (Useful to exclude video frames or other CPU-accessed textures)
GX2: Aspect ratio calculation now uses effective size of texture (after graphic pack rescaling) rather than original size
