DOSBox is a DOS-emulator that uses the SDL-library which makes DOSBox very easy to port to different platforms. DOSBox has already been ported to many different platforms, such as Windows, BeOS, Linux, MacOS X... DOSBox also emulates CPU:286/386 realmode/protected mode, Directory FileSystem/XMS/EMS, Tandy/Hercules/CGA/EGA/VGA/VESA graphics, a SoundBlaster/Gravis Ultra Sound card for excellent sound compatibility with older games... You can "re-live" the good old days with the help of DOSBox, it can run plenty of the old classics that don't run on your new computer! DOSBox is totally free of charge and OpenSource.

使用方法
　　1、安裝
　　2、運行
　　3、在輸入框狀態下z:>
　　z:>mount c d:dos ===>“z:>”這個是提示符“c”作為虛擬C盤 "d:dos"你要虛擬的文件夾位置。
　　簡潔的講，你把你要虛擬的文件夾位置換掉上面的 D:DOS
　　4、在剛才的提示符下輸入 c: ，這樣就切換到虛擬的c盤，也就是你要的游戲目錄
　　5、運行C目錄下的游戲，以后操作按DOS命令。
