Well Wine isn’t really a Windows “emulator” as they describe it, its more of an app to run Windows programs. For indexing and simplicity sake, I will call it a Windows emulator anyway, heh. Wine 1.1.33 is an Open Source implementation of the Windows API on top of X, OpenGL, and Unix. Think of Wine as a compatibility layer for running Windows programs. Wine does not require Microsoft Windows, as it is a completely free alternative implementation of the Windows API consisting of 100% non-Microsoft code, however Wine can optionally use native Windows DLLs if they are available. Wine provides both a development toolkit for porting Windows source code to Unix as well as a program loader, allowing many unmodified Windows programs to run on x86-based Unixes, including Linux, FreeBSD, Mac OS X, and Solaris. Wine 1.1.33 has the following changes:

* Gecko now installed at wineprefix creation time.
* Better support for certificates in crypt32.
* Improved sound support in mciwave.
* Some more Direct3D 10 functions.
* Many cleanups for issues spotted by Valgrind.
* Various bug fixes.
