00-04, 06-09, 0B-0E, 15-19 are all working levels using this code.
12 is the password screen.
13 is the Game Over screen.
14 is the password screen already set up.
1A is the title screen.
1B-1C, 21-24, 27-28, 2B work OK. They are quick cutscene sequences. The catch is that they're not meant to loop.
1F, 26, 33 partially works... it's another cutscene. However, the graphics are a bit glitched in at least one section.
20 is the opening.
29-2A accidentally lets the camera follow the main character, although it's a functional cutscene otherwise.
I don't think anything above 37 works at all.
Any value I did not mention should not be tried, mainly because of graphical glitches.

Select Start from the menu. The level you select will substitute the first shooting stage, and actually allows you to start later in the game than usual.
There might be graphical glitches because the graphics aren't properly loaded.
