- Also endian swap the BGnX and BGnY values on big-endian systems. This is a non-functional change, and is only meant to show that the endian swaps are indeed the correct choice for big-endian.
- Changing the display video source now updates the display window properly while the emulator is paused.
- Fix bug in the Screenshot Capture Tool where screenshots would have incorrect colors if taken on a PowerPC Mac.
- Fix bug in the Screenshot Capture Tool where screenshots would be completely black if a CPU-based pixel scaler on OpenGL was used.
- The OpenGL presenter's GPU tiering system has been changed to be more strict. This effectively pushes many older GPUs into lower tiers.
- The following pixel scalers now require at least a Low-Tier GPU (previously only required Bottom-Tier): 2xSaI, Super2xSaI, SuperEagle, HQ3x, HQ3xS, HQ4x, HQ4xS
- The following pixel scalers now require at least a Mid-Tier GPU (previously only required Low-Tier): 2xBRZ, 3xBRZ
- Due to the new changes to the GPU tiering system and allowed pixel scalers per tier, the Screenshot Capture Tool running OpenGL now allows pixel upscaling on the GPU instead of disabling it completely.
- Fix potential crashing bug that may occur if the target directory
isn’t found when clicking the Take Screenshot button.
- In the Display Layout dropdown panel, reposition the Display
Separation menu to be in the center section instead of in the leftmost
section.
- Has the positive side-effect of improving the OpenGL renderer's performance when many vertices are used.
- Also fix the vertex list double-buffering so that it actually works as intended.
- Note: The backlight intensity is only emulated on frontends with 3D-based display methods, such as OpenGL and Metal. CPU-based display methods, such as DirectDraw, SDL and Cairo, are currently unsupported.
- The old Tools > Save Screenshot As has been replaced with the new Screenshot Capture Tool.
- The new Screenshot Capture Tool allows screenshots to be configured to render with the same layout features as a display view.
- Screenshot captures now both render and save to file on their own independent threads.
- Screenshots are now captured using the Take Screenshot button, and files are now automatically named based on ROM name and timestamp.
- All of these features means that users can now rapidly take screenshots with their own custom layouts, all with little to no slowdown to the emulation.
- Also do a bunch of code cleanup and refactoring as a side-effect of adding these new features.
- Also be more consistent when recovering from an internal emulation halt.
- Also apply enabling the external BIOS, external firmware and firmware boot settings at load/reset time instead of at frame time.
- Framebuffer fetches no longer run on a CocoaDSThread, but instead uses a pthread directly. This can be done since framebuffer fetching only serves one function and always receives the same execution message, making a full CocoaDSThread a waste.
- SPU_Emulate_user() is no longer called on a separate thread, and instead is called in the emulation thread directly. For the typical SPU use case (SPU Sound Synchronization w/ Advanced SPU Logic), SPU_Emulator_user() becomes negligible, and so the threading overhead becomes unnecessary. In the use case where Dual SPU Synch/Asynch is used, Advanced SPU Logic is almost always disabled with it, and so the penalty of calling SPU_Emulator_user() on the emulation thread will be more than compensated by the performance increase of turning off Advanced SPU Logic.
- Also do some code cleanup/refactoring here and there.
- Fix a bug where Metal display views can block emulation execution if the user very quickly spams inputs while the input HUD is shown.
- Metal display views are no longer frame capped -- they can now run to their fullest performance potential, as fast as the host hardware will allow. This behavior is now consistent with OpenGL display views.
- As a side-effect, non-layer backed OpenGL display views also have a performance improvement.
