- Fix bug where switching between CPU-based and GPU-based filters in the DeSmuME Preferences display preview would sometimes fail.
- Fix bug where the DeSmuME Preferences display preview would show incorrect colors when using a CPU-based filter on PowerPC Macs.
Video Filters:
- Fix bug where the Scanline filter would show incorrect colors on big-endian systems.
- Fix some compiling issues if the C++ standard library is set to libc++ w/ C++11 support instead of libstdc++.
- Fix some compiling issues if compiling on OS X Leopard w/ Xcode 3.1.4.
- Fix the behavior of the Display Preferences filter preview.
- Fix an intermittent crash that sometimes occurs when creating a new display window.
- Fix a rare and mysterious crashing bug that sometimes occurs when initializing the HQ4x LUT.
- Fix a longstanding bug where audio frames were accidentally getting dropped when using N-sync and Z-sync methods. Greatly improves the audio quality of the N-sync method.
- Now that N-sync actually works as intended, it is now the default sync method. (N-sync has much better latency compared to the other sync methods, especially compared to P-sync, which was the previous default.)
- Update sync method tooltips to better reflect their actual behavior.
- Fix UI bug where the Advanced SPU Logic control text would get truncated on OS X Yosemite.
- Store the HQnx LUTs on the heap instead of on the stack. Fixes app builds from the Xcode 3 project, where the default stack size is smaller than when using the latest Xcode. (Regression for r5087.)
- Update Xcode 3 project so that builds actually work. (Regression from r5070.)
- Add shader-based equivalents to the following pixel scalers: 2xBRZ, 3xBRZ, 4xBRZ, 5xBRZ. (And yes, these are exact GLSL ports of Zenju's xBRZ scalers, not Hyllian's xBR scalers. These shaders are very demanding on your GPU, so users with older GPUs may want to continue using the CPU-based versions instead.)
- Add a preliminary GPU tiering system to help detect GPU capabilities and allow for better optimizations to be used on newer GPUs.
- Do some optimizations to the following shaders: Bicubic B-Spline, Bicubic Mitchell-Netravali, Lanczos3, EPX.
- Change the shader-based EPX+ color comparisons to be more true to the original CPU-based algorithm.
- Improve color blending on the Deposterize shader.
- Fix possible invalid memory access crashes when Y-sorting, most notably, in Super Mario 64 adventure mode. Using std::stable_sort() instead of std::sort() should have little to no performance impact since we're not sorting a lot of elements here. (Regression from r2436.)
- Initialize the HQnx LUTs only once, instead of doing it per display window.
- Fix issue where the HQnx LUT init code was causing extremely long compile times. (Regression from r5087.)
- Added CPU mutex functions gdbstub_mutex_init/destroy/lock/unlock, which govern access to NDS_ARM9 and NDS_ARM7 structs.
- Added locking and unlocking of the mutex to gdbstub.cpp/processPacket_gdb() and NDSSystem.cpp/NDS_exec()
Cocoa, CLI, GTK, Windows ports:
- Added mutex initialization and destruction to main() functions (cocoa/cocoa_core.mm, cli/main.cpp, gtk/main.cpp, windows/main.cpp)
- Have video from CPU-based pixel scalers transfer to GPU via DMA. Should improve performance on pixel scalers with large scaling sizes, such as HQ4xS and 5xBRZ.
- Add method VideoFilter::SetDstBufferPtr() - allows users to use their own destination buffer instead of having to use the VideoFilter object's internal buffer.
- Delete the Legacy Cocoa port. (Not only was the Tiger build broken in several ways, but all features from the Legacy port have been subsumed into the main Cocoa port now. Therefore, the Legacy port is no longer necessary.)
- Remove the "Xcode 4" and "Xcode 5" project files. These files have been superseded by the one project file "Xcode (Latest)".
- Do a massive cleanup of the #include and header structure.
- Remove a lot of unnecessary dependencies in the headers.
- Make headers responsible for including what they need for themselves. This makes the headers more independent of where they are in the #include order.
- Relocate some structs/classes to more logical locations.
- Clean up some platform-specific #ifdef stuff.
- Add a new developer-oriented build scheme called "OS X App; dev+" to the Xcode4 and Xcode5 projects.
- Add preliminary GDB stub support to the dev+ build. (Use the menu option Tools > Show GDB Stub Control.)
GDB Stub:
- Do some minor cleanup on the GDB stub init code.
