Kali (software)
Kali is an IPX network emulator for DOS and Windows, enabling legacy multiplayer games to work over a modern TCP/IP network such as the Internet. Later versions of the software also functioned as a server browser for games that natively supported TCP/IP. Versions were also created for OS2 and Mac, but neither version was well polished. Today, Kali's network is still operational but development has largely ceased.
