- To note: This fix to Pokemon Black/White does not require
CommonSettings.pokehax to be enabled.
- The CaptureEnable flag is now only read at the start of line 0,
instead of being read directly from the DISPCAPCNT register per line.
In addition, this same state is held all the way through line 192.
- The CaptureEnable flag is now reset at the start of line 192, instead
of near the end of line 191 H-blank. (This is the proper behavior
according to GBATEK.)
- The CaptureEnable flag is now only reset when the VRAM configuration
is LCDC, instead of always being reset. This makes it possible for this
flag to remain set on line 192 if the VRAM configuration is changed to
a non-LCDC configuration.
- CommonSettings.pokehax is now initialized to false.
- Fix a small bug when setting CommonSettings.pokehax via the command
line.
- Fixes custom VRAM reads for OBJ bitmap reads when the read location
doesn’t start at line 0. This behavior is now consistent with how BG
extended layers do it.
- Display views now take the Deposterize filter into account when
determining the direct-to-CPU-filtering state.
- GPUSubsystem now combines the RGB666-to-RGB888 conversions and master
brightness steps into a single postprocessing step.
- Do some minor code cleanup.
- An Apple Metal display view requires macOS 10.11 El Capitan or later,
in addition to a Metal-compatible GPU.
- Apple Metal display views have significantly lower CPU usage then
OpenGL display views.
- OpenGL display views now use a shared fetch object to fetch the emulated GPU framebuffers and store them in shared textures within a shared context. In conjunction with the new double-buffering support from the last commit, this eliminates the copying between the framebuffers and each display view.
- OpenGL display views now use shared HQnx LUT textures, rather than having to initialize and maintain a copy of the LUT textures for each display view.
- OpenGL display views no longer perform any rendering while their associated NSView is hidden, improving the performance of creating new display views.
- OpenGL display views can now DMA directly from pinned-memory both custom-sized framebuffers and CPU-pixel-scaled native-sized framebuffers at the same time.
- Framebuffers are now page-aligned on 4KB boundaries. This is to
improve performance when using the framebuffers directly as pinned AGP
memory.
- Framebuffers are now double-buffered. The target buffer index is now
tracked using the bufferIndex field of NDSDisplayInfo.
- Clients may no longer supply their own buffers to
SetCustomFramebufferSize(). Clients must use the pointers supplied by
NDSDisplayInfo.
- The frameskip flag is now set only on line 0 and remains consistent
for all 192 lines of rendering.
- GPUSubsystem no longer needs a special allocater/deallocator for
itself, so it has been reverted back to a standard C++ new/delete.
- Add a GPUClientFetchObject helper class as an aid to clients that
need to read out the framebuffers. (Should probably move to its own
file at some later date.)
