If you are about to collide
with something (like a building), in all-range
mode, then just u-turn and
you'll go right through it, damage-free!
When you fight the last guy
in Coneria (on the easy route) do a
forward barrel roll through
the boss's legs and you will get an
extra life. You should do
this when you first face him and make
sure that you don't hit him
at all through out the whole somersault.
Complete the game in Extra
Mode and wait for the end of
the credits. Depending on
whether you went through Venom
1 or 2, you will get two different
pieces of art. One is a
picture of all the characters
in the game's heads, the other
is a cool portrait shot of
the Star Fox team with the word "Great!"
