I GOT IT! alright so- steps to take:

first locate your war2.ini and change the first line to look like this cdpath=d://

Second, make sure all the files are in one folder in /home/pi/RetroPie/roms/pc You can name it whatever you like. I called mine “warcraft2”

Next open up dosbox and type:

mount d "/home/pi/RetroPie/roms/pc/warcraft2" -t cdrom

then type C:

then type warcraft2\WAR2.EXE
