Smb3free.exe
From Screamer Wiki
Smb3free.exe is a Smb3free.cf fan-sequel. The Intro is creppy, but after the Intro, the main menu appears and seems normal. When you open one of the files, the world map appears. There's one Level, which is actually fake. When you enter the level, a picture of Regan MacNeil pops up with a scream, then the game crashes.
