FC模擬器HalfNES發佈新版, 更新如下:

0.023 (1/4/2011)
Bugfixes:
-The Reset command didn't do anything, now it does.
-Gradius and Devil World work properly again and Back to the Future works better (I used && when what I meant was ||).
-I now realize that file loading doesn't work very well on a Mac (and the file dialog is terrible too!), so I'll work on that.

Wow, it's been a while.
Added Player 2 controller support, can remap the buttons in the settings.txt file.
Improved rendering: Gauntlet runs full speed on my computer when it didn't before, the status bars of Zelda II and Ninja Gaiden now look right, in general performance is about 20 percent better because the drawing code is more efficient.
Back to the Future works but has random unexplained glitches.
Made a few additional tweaks to the MMC3 code, now Might and Magic works but SMB3 is unchanged.
Also eliminated a potential crash after attempting to load a game with an unsupported mapper.
Changes to the audio code: Excitebike and a lot of other early games that used the sweep feature on the square wave channels should be correct now,
Super Mario Brothers finally sounds right.
Also, this works. http://kkfos.aspekt.fi/2010/11/14/4-bit-pcm-on-nes-using-the-pulse-channel/

0.021 (12/15/2010)
Added mappers 66 and 71 (SMB/Duck Hunt and Codemasters, respectively).
Also made background sprites actually render behind the background, and fixed sprite priorities for 8x16 sprites (They were reversed before).
If you're having trouble with SMB3, make sure that you have the PRG1 version of the ROM.
Even then, it still freezes on the title screen half the time when you press Start...
if it does this, reload the ROM and try it again. Once you start the game successfully though it should be playable. There's just something the title screen does that throws timing off.

0.020 (12/8/2010)
Fixed the missing sprites bug and games with a status bar on the bottom.
Super Mario 3, Tiny Toon Adventures, Marble Madness, Kirby's Adventure and Battletoads are playable. (Tiny Toons doesn't quite put the status bar in the right place, but it's not too far off.)
Fixed 4-screen mirroring (Gauntlet) Also added mapper 34 support (Deadly Towers) Dragon Warrior 3 + 4 still won't start, Zelda II and Crystalis still have problems.

0.019 (12/1/2010)
Fixed the worst of the scrolling bugs. Contra, Castlevania 2, Blaster Master, and many other games are now actually playable.
Also, it seems that Yo Noid! crashed the emulator (because bitwise and is NOT the same thing as modulus when you don't have a power of 2!) so I very reluctantly fixed that as well.
Known Issues:
-Jump sound doesn't cut off in world 1-2 of SMB
-Zelda II won't scroll correctly until real sprite 0 hit is implemented
-Most games with a status bar on the bottom won't display that bar
-Sprites missing in Tiny Toon Adventures, Little Nemo
-DuckTales status bar uses wrong graphics
-Mario's eyes are missing in SMB2
-Basically every racing game uses the same scrolling trick that won't look right
-SMB3 and Marble Madness both crash and Silver Surfer resets itself

0.018 (11/24/2010)
Timing fixes - Kid Icarus, Solomon's Key, Adventures of Lolo 2, Jackal are now playable.
Fixed a couple issues with the audio as well. (Periodic noise works, and channels don't buzz when the periods are set to zero.)
Mega Man 2 is where this improvement is most noticeable.
The OS default look and feel is used instead of the Java default now, which means the Open dialog is improved.
Saved games should always save on close now, no matter how the window is closed.
