Very good, naming this "Super Mario Crossover v3.1.21.swf". Thanks! Got several of these but this is by far the biggest I have saved.
But man it annoys me that the dev doesn't allow you to play in fullscreen. There's a fullscreen option in general settings but when you select it there's a message: "Full screen mode is only available on the developer's website. Would you like to play the game there? No/Yes" So it isn't fully intended for offline use.
Very arbitrary. And you can't right-click and "select show" all to resize the flash projector because there's a black overlay. HOWEVER pressing Ctrl+F works in the projector, to force it into fullscreen. Gets a little bit blurred though, I guess it renders the image frames to the default size and it is then stretched out by the projector.
