DxWnd

Features:

• This software permits users to run fullscreen games and programs in a resizable window.
• This software can slow down or speed up the game clock (time stretching), which helps with games that run too fast on modern PCs.
• It is specifically designed to support legacy programs, with fixes for DirectDraw, Direct3D and OpenGL games, color depth problems and emulation of CD audio from ripped tracks.
• This software keeps a log of operations and shows program status, and it offers a virtual joystick controlled with the mouse or keyboard.
• This software is portable: it is distributed as an archive and runs from any folder once unpacked.

DxWnd is a free "window hooker" that lets users run old games that in the past may simply not have been able to run on modern Windows at all. It intercepts the system calls a program makes and changes their behavior, so a game that insists on taking over the whole screen runs inside a normal window. Each game gets its own profile with settings for video, mouse, DirectX and timing, and the list of programs can be saved and imported. Besides running the games, it improves their behavior by slowing down or speeding up the action and adjusting resolution and window size. DxWnd is developed by ghotik and published on SourceForge, where new builds still appear regularly. In conclusion, this is a useful tool for anyone who wants to play "old school" Windows games from the 1990s and 2000s on a modern PC.

It has the ability to run fullscreen programs in window mode and fix compatibility problems of old games.
