Cheat mode
Press [LS], [RS]x2, [LS], [RS],
[LS]x9, [RS], [LS]x6, [RS], [LS]x4,
[RS] at the options screen (with Gir Draxon's face displayed).
Gir Draxon's eyes will glow red and the word "Cheater"
will appear to confirm correct code entry. The Boss will appear
after the first wave of enemies is destroyed. During the game,
pressing [LS] will restore shields, holding [LS] will
make the Raven invincible, and [RS] will stop enemies.
Level warp
Destroy the lower-left obstacle (seven o'clock position
on radar) on level 1 to advance three levels. This will require
multiple shots, and works even with the difficulty on "Practice."
Shoot at a similar obstacle at the same location at this new level
to advance to the end level.
Cruise control
Hold [LS] or [RS] to keep the Raven at whatever
speed is set with [Up] and [Down] (even in reverse).
The Raven will stop when it runs into an object.
