get a windows version of the emulator, like mame32 or mame32plus! either of those work the same, and will not show a dosbox when loading. Install the app in the folder your using and rename the main program (mame32gui.exe or mame32pgui.exe) to mame.exe. The emu will run and load the same, although you may have to regenerate your gamelist, but will not show the dosbox! Good luck, and any more questions just holler.
