- Count clock cycles to synchronize SA1 with S-CPU properly - Only allow instant IRQ when toggling IRQ. Fixes WWF - Wrestlemania - Refactored APU output code to buffer less on the client side. Removed 8-bit, Mono, and Reverse Stereo options - Consistently handle interlacing when we skip frames - Changed APU clock to reflect nominal values for original hardware - Fix C4 square instruction regression GTK+: - Switch from autotools to Meson build system - Readd glFinish option as alternative to glFenceSync - Fix size fallthrough with xBRZ filter - Fix loading of key bindings with spaces in them and modifier keys used alone - Add support for libretro ".slang" shaders to OpenGL driver - Use a cleaner onscreen font - Trap errors to allow OpenGL <= 2.1 to run again - Break display settings up to make it easier to access hardware accel section Win32: - Don't display Joypad 2 pressed keys if disabled - Add support for libretro ".slang" shaders to OpenGL driver - Removed glitch-prone DirectSound audio driver in favor of a generic Wave Out driver - Moved sound sync to drivers to be more reactive. This makes sound sync and dynamic resampling work more reliably - Cleaned up dialog boxes to be more consistently spaced - Fixed TVMode filter in Direct3D and OpenGL modes - Fixed an interaction slowdown with OpenGL and Blargg NTSC filters
