here make your video configuration like this in mugen.cfg [Video]  ;Enter the width and height of the resolution you want to set here.  ;The optimal resolution is 320x240, but if your video card has problems  ;You may want to try 640x480. Width  =640 Height =480    ;This is the color depth at which to run MUGEN. You should set it to  ;16 bit color unless your video card has problems with it.  ;16-fastest, 24,32-slower, 8-slowest/worst Depth =16    ;Set this parameter to 0 to disable screen stretching, and set it to 1 if  ;you want to scale it up to fit the current resolution. Stretch =0    ;Set this parameter to use a resolution-doubling filter. You will  ;need a fast machine to use these filters. You will need to increase  ;the screen resolution to at least 640x480 for these modes.  ;0 - off  ;1 - diagonal edge detection  ;2 - bilinear filtering  ;3 - horizontal scanlines DoubleRes =0    ;Choose from "1" for VESA1, "Linear" or "Banked" for VESA2, and "3" for  ;VESA3.  ;Note: VESA1 is very slow on certain video cards, especially the newer  ;ones. "Linear" or "3" is usually the fastest for new cards.  ;Default is "Linear". Vesamode =1    ;Set to 1 to enable vertical retrace synchronization. VRetrace =0   I forogt where to add sound support
