Ecco the Dolphin -- Sega CD
===========================

Debug Menu- 
During the game, make Ecco turn in the opposite
direction. While in mid-turn, pause the game 
just as Ecco directly faces you (as though he's
looking out the screen at you). While the game 
is paused, press RIGHT, B, C, B, C, DOWN, C,
UP. Now you'll access a menu that lets you 
cheat like crazy.
