Free windows software for linux

GAIMnOSD is a plugin for GAIM allowing to print events outside of any windows in TV menu style. The plugin uses the XOSD library for output.

GAIMnOSD project allows setting the size, position and the color of the notification messages.

Wine is an Open Source implementation of the Windows API on top of X 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, and Solaris.
Main features:
Binary Compatibility
- Loads Windows 9x/NT/2000/XP, Windows 3.x and DOS programs and libraries
- Win32 compatible memory layout, exception handling, threads and processes
- Designed for POSIX compatible operatings systems (eg. Linux and FreeBSD)
- ``bug-for-bug compatibility with Windows
Graphics
- X11-based graphics allows remote display to any X terminal
- X11, TrueType (.ttf/.ttc) and Windows Bitmap (.fon) Fonts
- DirectX support for games (limited Direct3D support)
- Printing via PostScript driver or legacy native Win16 printer drivers
- Enhanced Metafile (EMF) and Windows Metafile (WMF) driver
- Desktop-in-a-box or mixable windows
- Windows MultiMedia (WinMM) layer support with builtin codecs
Allows Windows program to interface with:
- Sound devices via ALSA, OSS, ARTS, JACK, and libaudio etc
- Multi-lingual keyboards and CJK input method support via XIM
- Modems, serial devices
- Networks (TCP/IP and IPX)
- ASPI Scanners
- Windows Tablets via XInput (eg. Wacom)
Wine API
- Designed for source and binary compatibility with Win32 code
- Win32 API test suite to ensure compatibility
- Compilable on a wide range of C compilers
- Permits mixing of Win32 and POSIX code
- Permits mixing of ELF (.so) and PE (.dll/.exe) binaries in one address space
- Win32 compatible header files
- Automatically generated API documentation
- Resource compiler
- Message compiler
- IDL compiler
- extensive Unicode support
- Internationalization -- Wine supports 16 languages
- Built-in debugger and configurable trace messages
- External memory checker support using Valgrind
- Sample programs
Enhancements:
- Direct3D support on top of WGL instead of GLX for better portability.
- Many DirectSound fixes.
- Still more gdiplus functions.
- Many crypt32 improvements.
- Lots of bug fixes.

Cygwin project is a DLL which provides a Unix emulation environment for Windows.
The Cygwin environment provides a complete port of such development utilities as gcc, binutils, gdb, make, etc., as well as a vast number of useful utilities.
Enhancements:
- Many bugfixes were made and a few new functions were exported.

NdisWrapper implements Windows kernel API and NDIS (Network Driver Interface Specification) API within Linux kernel.

A Windows driver for wireless network card is then linked to this implementation so that the driver runs natively, as though it is in Windows, without binary emulation.

Buscayasminas project s an open source "Minesweeper" alike game totally written in DHTML (JavaScript, CSS and HTML) that uses mouse and keyboard optionally.

This cross-platform and cross-browser game was tested under BeOS, Linux, *BSD, Windows and others.

Linux Commander is a powerful file manager for the X Window System.

It is partially modelled after Window Commander for Windows.
