HalfNES v0.049 - 模擬器

http://code.google.com/p/halfnes/

The NES emulator HalfNES has been updated.


0.049 (7/9/2012)
-CPU core is much improved. All undocumented opcodes should now be
implemented and cycle timing is more correct.
-Fixed Low G Man crashing after the first boss
-APU is now synchronized exactly with CPU (lowers performance, but fixes
Dreamworld Pogie)
-Made DMC sample channel timing more accurate, which fixed Bee 52 and several
DPCM letterbox demos and made Fire Hawk at least show the titlescreen/intro.
(Still crashes in game.)
-Made the audio high pass filter more aggressive to eliminate clipping and
noise
-Fixed VRC7 audio envelopes (Rate was right but notes couldn′t be turned off
while in the decay phase. Now that works.)
-Fixed PPU OAM reading to pass oam_stress test and used blargg′s NES power
up palette
