[The Fifth Horseman]

I've explained it before a dozen times.
You can create modified shortcuts and config files that run specific games with specific DOSBox configuration.
It takes about 5 minutes per game, and once you're done you have a shortcut that immediately launches DOSBox, automatically starts up the game and exists the emulator when the game terminates.
No frontend neccesary.

I've set up over a hundred games this way - it's pretty straightforward.
