- If you have an ARM processor, expect anywhere between 10% to 50% improvement to CPU emulation performance for most games.
- But it isn't quite for prime time just yet. There is a crashing bug related to munmap() at emit_core.cpp:93 that causes the app to crash when resetting the emulator after a game has already been run.
- The Cocoa port now enables the new ARM JIT engine for Macs running Apple Silicon processors, but only for dev+ builds. This is due to the crashing bug noted above.
- There should be no functional changes in this commit. We're simply mirroring the latest SDK for changes to come.
- Fix all deprecations, with the exception of [OEGameCore changeDisplayMode]. This one will be quite involved.
- The features contained therein aren't ready for prime time, and so they are being pushed out to the next release.
- These menu options are still accessible on dev+ builds.
- This change basically returns us to using 1D textures for color LUTs instead of using uniform arrays. 1D textures seem to be more compatible for most older hardware.
- Unfortunately, while most older GPUs will work better with this change, this may break the OpenGL renderer on even older GPUs, such as the GeForce 7800 GT (circa 2005).
- I'm estimating that more old GPUs benefit from this change than not, and so using 1D textures is what will stand. The vast majority of users will be using hardware newer than this, and so anyone who can't run OpenGL renderer in 2022 can just switch to SoftRasterizer.
- This bug was found by enabling FIXED_POINT_MATH_FUNCTIONS_USE_ACCUMULATOR_SATURATE. Since this macro is disabled by default, this commit should not affect any normal operation.
- Apparently, there are some Macs that have Intel Haswell CPUs that can run macOS versions earlier than El Capitan, so Metal.framework must be weak-linked for the Final Release.
- All x86_64h Debug builds and all Apple Silicon builds still retain strong linking with Metal.framework.
- This is probably super paranoid and completely overkill, but it makes me feel better to do this. Now there is absolute certainty that nothing can disrupt the drawable order in between rendering and presentation. Microstuttering from mis-ordered drawables can no longer happen.
- Fix a bug where running DeSmuME on a Mac with a non-Haswell 64-bit Intel CPU would fail to switch the GUI icons into Dark Mode, despite the user running Mojave or later.
- Fix a bug where the GUI icons would occasionally fail to correctly switch between Light Mode and Dark Mode if the user changed the system appearance in System Preferences while running Mojave or Catalina.
- Add a new menu option in "Tools > App Appearance Mode" to manually force DeSmuME's app appearance to reflect Light Mode or Dark Mode. (Only available on dev+ builds.)
- Since the executable can now contain 5 binary slices, having the detailed info available can provide extra insight on the user's runtime environment.
- Hardware microphone authorization is now requested on app startup instead of when a ROM is loaded.
- CoreAudioInput is now better at handling situations when the hardware mic is not available, fixing some bugs with the mic level indicator.
- Add some helpful tooltips in the Microphone Settings panel when the hardware mic is not authorized.
- Add a new idle mic icon to denote when the hardware mic is not available. (The gray color should denote a 'software only' status.)
- Further brighten up the microphone icon for when software samples are active to help with visibility when running Dark Mode.
- Access to the matrix stacks has been simplified to the point where MatrixStackInit() and MatrixStackGet() are now obsolete. These functions have been removed.
- Also adds the AVFoundation framework to the "Xcode (Latest).xcodeproj" file in preparation of new UI related to dealing with macOS Mojave's microphone permissions.
- Also do some minor bug fixes with some floating-point functions.
- Also remove __vec4_dotproduct_vec4_fixed_SSE4() since the function didn't work anyways, and since we now have __vec4_dotproduct_vec4_fixed_NEON() to use as an actual working reference.
- This refactor was done to support future additions of SIMD functions using ISAs other than SSE / SSE4.1.
- Add support for fixed-point math functions using accumulators that saturate, following the GEM_TransformVertex() function. This feature requires new testing, and has been disabled for now in order to retain the previous behavior.
- Remove the obsolete and unused functions _MatrixMultVec4x4_NoSIMD() and vector_fix2float(). If non-SIMD testing is required, it should be easy enough to comment out the SIMD code paths in the appropriate function in favor of the plain C code path.
- The only OpenGL version with a revision number is v1.2.1, but the Cocoa port will always use v2.0 or higher. So let's remove the revision number to make things look cleaner.
- Also change the tags "DESMUME RUNTIME INFORMATION" to "DESMUME TROUBLESHOOTING INFORMATION", which is more explanatory when the information is copy/pasted into whatever text field it appears in.
- I solved it by simply reloading the entire outline view instead of picking and choosing specific items to reload. Due to the relatively few amount of items in the outline view (less than 1000 items), reloading the entire outline view is still very fast, even on a PowerPC Mac.
- MainMenu.strings files can still be generated from builds from the "DeSmuME (XCode 3).xcodeproj" file, which does result in a cleaner file to begin with.
- Add line for the Video Output Engine. Backend type (OpenGL or Metal), version, and renderer information are all reported.
- Remove section breaking dashes, as this causes GitHub's comment parser to reformat the runtime info in unpredictable ways.
- To compensate for removing the section breaking dashes, add delimiters for the beginning and the ending of the runtime information.
- If the Active Cheat Count is 0, then just report "NO" for Cheats, as this is functionally equivalent, but less confusing to read.
- Commit 9ccc791 was, more or less, a straight port of the SSE2 code, making it less than ideal. This updated version uses more NEON-only instructions to further improve performance.
