This is an
old mugen tool but apparently there are a lot of people who don't know about it.

Just download this and extract it somewhere. This tool is called stageviewer, it's very small and super easy to use. Very self explanatory and super useful and easy.

Just drop a stage .def file on the screen and the stage appears as if it were in a mugen window. You can disable the character from appearing and take a quick snap shot of the stage by pressing F8 or by selecting snapshot in options.
You can even set a directory to all your stages in your mugen stage folder so you can scroll between stages and preview them instantly through a list.
You can use this tool for...
*Stage Making/Editing
*Quick Preview of Stage Downloads
*View Stages as Recreational without Mugen
*Youtube Assist for Mugen Videos
*Deleting Unwanted Stages
