[The Fifth Horseman]

well, dosbox slows down the PC when I needed it to speed up...so dosshell was downloaded as an emergancy attempt and it worked..

Frontends provide a fool-proof user interface, but don't automagically make DOSBox better.
Everything a frontend can do with DOSBox configuration, you can do yourself with a little effort. To speed up DOSBox you first set the Core to Dynamic and Cycles to Max. Then you can change the output mode, set a lower fullscreen resolution (640x480 recommended), increase frameskip (frameskip=1 gives no practical difference, frameskip=2 or 3 might result in a slight choppiness of the graphics but will speed them up even more), disable scalers (for games that use a lower native resolution than 640x400 or 640x480, a Normal2x scaler is still neccesary) and disable some of the emulated sound devices (GUS, Tandy, Disney, MPU-401 and PC Speaker all can be disabled to save some CPU power).
