DOSBox-X is a comprehensive DOS emulator, supporting DOS applications including Windows 3.x and Windows 9x, and striving to provide accurate hardware emulation. It is based on the original DOSBox and includes features from a number of forks including SVN Daum, ECE, DOSBox Staging, DOSVAX, and vDosPlus.

Its features include: - a built-in drop-down menu - a graphical configuration tool - support for save-states - NEC PC-98, AX, and J-3100 emulations - DOS/V support for Chinese, Japanese, and Korean language support - support for CONFIG.SYS commands - printing support - long filename support - DOS SHARE emulation - wheel mouse support (including the CuteMouse wheel mouse API) - 3Dfx Voodoo chip emulation - NE2000 emulation - MT-32 emulation

DOSBox-X isn't a direct upgrade from DOSBox, but DOSBox users should be able to use DOSBox-X without difficulty.
