FC模擬器puNES發佈新版，更新如下：

0.71 (Bugfix release)
In linux version the menu bar is not displayed correctly. Fixed.

0.70
Fixed some memory leaks (thanks to Valgrind).
A restriction in the code of mapper UnROM prevented the start of the "Battle Kids 2 - Mountain of Torment". Fixed.
*** Windows Version ***
In this version I've rewritten from scratch the Audio stack. I abandoned the use of SDL replaced with the XAudio2 (DirectX). With this I hope I have permanently removed the audio lag problem experienced by many.
Improved handling of reading from gamepads, now the sensitivity and accuracy are significantly better. Increased compatibility with many gamepad (thanks OldGhost).
Fixed a bug which allowed the start of the screensaver during the game session.

0.69
MMC3A and MMC3C are now full implemented.
Fixed a bug in MMC3 code and now the status bar in Mickey's Safari in Letterland is displayed correctly.
Added an option in the Audio Settings that enables the sound output of a early Famicom-clone consoles (swaps the duty cycles 25% and 50%).
Fixed a bug introduced in a previous version that did not allow the start of the "Batman - Return of the Joker".
Added support for Windows 8.
Added CLI option "--portable" for run puNES in portable mode (is no longer necessary to rename the executable even if it is still possible to do so for backwards compatibility).
Fixed the display of the parameters of the command line in the Windows version.

0.68 (bugfix release)
Correct a bug introduced in version 0.66 that in some circumstances, did not allow the filling of the audio buffer in time, producing a sound skipping.

0.67
Correct the support for the D-pad in the Windows version (reported by Alterac).
In the "Standard Pad" setup added a button (1 for Keyboard and 1 for Joystick) to unbind all buttons (suggested by Alterac).
Implemented the support of Drag & Drop of roms directly in the emulator window to load them (suggested by thefox).
Other small bugfixes.

0.66
Fixed some little bugs in the apu engine (sweep and triangle) and implemented the non-linearity and interaction between audio channels. Now (finally) the apu_mixer (http://wiki.nesdev.com/w/index.php/Emulator_tests) test roms works well in puNES (I hope).

0.65 (bugfix relase)
Fixed a small bug introduced in version 0.64.
Adjusted slightly to stereo mode

0.64
Rewrite from scratch the audio subsytem and now there are two new options in the "Audio" menu, "Low" and "High" quality.
"Low" is the old engine, "High" is the new engine. Just try to hear the difference.
Fixed many bugs in APU emulation which is now much more accurate.
Added the ability to have a portable version of the emulator. Just rename the executable:
Linux:
punes32 -> punes32_p
punes64 -> punes64_p
Windows
punes32.exe -> punes32_p.exe
punes64.exe -> punes64_p.exe
When the executable becomes a portable version, it create and use the folder where is the exe as the root folder.

0.63 (bugfix relase)
Correct a pitch and envelope problem reported from Dwedit (thanks for your help and for your patience).
Fixed a bug that could create sound skip and noise in the audio buffer.
Correct a bug introduced in version 0.62 of win64 that did not allow the emulator to start correctly.
Other small bugfixes.
