I first off want to say that this an EXCELLENT app. I'm a MameWah user, but if you keep it up, I think I and many others will make a permanent switch.
One feature I'd like to see is a NODOSBOX parameter integrated into the app. When I launch a game, I'd rather not see a window with the command-line MAME running before the game starts. The goal is to hide Windows.
Keep up the good work. I love it already. Very pretty.
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.
