  • CPU: Optimized GamePak prefetch buffer emulation

  • CPU: Reading prefetched GamePak memory engages the GamePak prefetcher.

  • CPU: Delay all IRQs by four cycles (fixes James Pond)

  • CPU: Handle pipeline flush for halfword reads

  • CPU: Force next ARM instruction fetch to be sequential if the condition isn't met.

  • CPU: Optimized ADC and SBC flag calculations

  • DMA: Ignore repeat-flag for immediate DMAs

  • DMA: Mask source and destination addresses on write.

  • DMA: Properly disable non-repeating FIFO DMA (fixes #97)

  • Timer: Greatly optimized emulation efficiency, timers now are scheduled.

  • Memory: Fix unaligned S16 reads from out-of-bounds ROM

  • Memory: Allow read/write to POSTFLG register

  • Memory: Allow read from WAVE_RAM registers

  • Memory: Fix unaligned S8/S16 reads from SRAM

  • Memory: Handle DMA reads from open bus addresses (fixes #109)

  • Memory: Improved GPIO bus emulation

  • Memory: Force-align 16-bit expanded 8-bit VRAM and PRAM writes.

  • PPU: Raise H-blank IRQs after 960 cycles instead of 1006 (fixes #89)

  • PPU: Handle OBJ priority hijacking (fixes #99)

  • PPU: Respect per-scanline cycle limit for OBJ rendering (fixes #98)

  • PPU: Handle odd tile numbers in 256-color OBJs (fixes #106)

  • PPU: Emulate tile number limit for 256-color OBJs

  • PPU: Latch internal affine registers on mode switch (fixes #90)

  • PPU: Handle setting V-count setting to the current V-count value.

  • PPU: Make V-count IRQ edge-triggered

  • PPU: Fixed broken semi-transparency logic

  • APU: Clamp samples before converting to S16 format (fixes #100)

  • APU: Use BLEP resampler to improve quality of direct audio.

  • RTC: Fix off-by-one error in the day of month.

  • GameDB: Added save type override for Acrobat Kid (Japan)

  • GameDB: Added save type override for Baldur's Gate - Dark Alliance

  • GameDB: Added save type override for 007 - Everything or Nothing

  • GameDB: Added save type override for Super Monkey Ball Jr.

  • GameDB: Fixed save type override for Classic NES - Legend of Zelda

  • Common/DSP: Linearly interpolate CosineResampler lookup-table

  • Common/DSP: Added a BLEP resampler

  • Miscellaneous: Do not sync to audio by default

  • Miscellaneous: Experimental, optional hack to increase audio sample rate in games which use the M4A/Sappy sound engine. This will break games and is thus not turned on by default.
