At the Virgin logo, quickly hit Up, Up, Up, B, B, Y, Y, and 
Select.  You'll then hear a percussive jungle sound.  Hit Up, 
Down, Left, Right, B, Up, Y, Left, Select, and Down.  Enter all 
these button presses within 10 seconds, before the Virgin logo 
fades.  Go to the Options menu, and you'll see a level select 
number at the top.  Use A to pick the chapter you want.  Scroll 
down to Cheat, and use A to select the special ability you want 
to use.  The most helpful cheat is number five, which enables 
Mowgli to fly (L), move in slow motion (R), and start with up 
to 99 weapons.
