This uses Auto Hotkey as an auto splitter. It is designed to work with newer versions of MAME (post 0.117-ish) in windowed mode. It searches for colored pixels that only appear on the "How High Can You Get?" screen and splits when it finds them. If you die on a screen, you'll need to undo that split when the stage reloads. Since Auto Hotkey is looking at exact pixels, you might have to make adjustments depending on your screen resolution.
