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
