Super jumps: Press Up(2), Down, Left, Right,
B, Start at the title screen.
Level select: Press Up, Down, Up(2), Down,
C, A, B at the title screen.
Hint: Double attack: When either one of both players are fighting the two
dragons close to the end of level 1, usually the two sticks acquired
from those two walkers earlier in the level are left behind in
that area while either player flies off on the dragons instead.
If either one of the players has one of those two sticks in their
hands when they board one of those two dragons, then they will
actually take the sticks with them while they fly off on those
dragons and they will use those sticks to attack. Instead of just
the rather fast fire-shooting of the dragons themselves, you can
also have the stick to attack with, making for an actual double-attack.
Also, if you get close enough to the rest of the enemies for the
rest of the level, you will then be able to dual-attack them that
way.
