一般mugen里都有data的文件夹打开然后找mugen.cfg，用笔记本打开，在里面找到[Video Win]
;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 =1
;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;2
;DirectX mode
;Choose from Hardware, Software, Windowed, Overlay, Safe and None
;Hardware and Software run in full-screen. Windowed and Overlay
;run in a window. The windowed modes require you to set Depth to
;whatever color depth you are using for you desktop. The best results
;are when you run in 16-bit color. There is no advantage to running
;in 32-bit color. If Hardware, Software and Windowed fail, try Safe.
;None uses GDI to draw, so it's very slow. Use None only if
;you cannot get anything else to work.
;Overlay is not supported by all video cards, but can be faster than
;Windowed if it works.
DXmode =windowed
;Set to 1 to enable vertical retrace synchronization. Do not enable
;if BlitMode = PageFlip.
VRetrace =0
;Drawing mode
;Choose from Normal and PageFlip
BlitMode =pageflip

这就是分辨率
Width =640
Height =480
先怎么调就怎么调，适合你的电脑屏幕就行了
