Autosplitter settings

• Normal Levels
• Boss Levels
• Switch Palaces
• Level Room Transitions
• Castle/GH Room Transitions
• Bowser Phase Transition

The autosplitter does not seem to detect level completion for fortresses (defeating reznor), completing the sunken ghost ship by collecting the orb, or regular levels finished using yoshi wings (eg: Cheese Bridge Area, Way Cool, Valley of Bowser 2).
