Hi ! I got Dosbox running and im playing ultima 8 atm but i dont know how to save the game so i dont have to do everything again after i quit dosbox :(

Please help me.

You can press the ESC button during playing the game and choose to save a game. Or you can press the F8 key, I think, to quick-save a game and some other key to quickload it. The exact keys are described in the .txt-files supplied with the game. ;)
