NanoboyAdvance 1.2

GBA模擬器 NanoboyAdvance 發布新版，更新如下 :

• 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.
