To find the black hole, choose course one and getto the asteroid belt. There go through the course as usual but when the long chain of asteroids appears, wait until they come very close then
destroy them. After you do that to all of them an asteroid with a face appears. Keep shooting it until it turns into a black hole and go through it.
This trick requires the Plasma Cannon.
To find the bonus level, choose course three and get to the
second stage. In the asteroid belt you'll
find two asteroids which are much larger than the others. Use your Plasma Cannon to blast the large asteroid on the lower right-hand side. A bird will appear. Fly into it to enter the Bonus Level!
The boss is a huge slot machine, which is extremely hard to beat. You have to shoot it until it
spins three "7"s. When you beat it, the credits come up as if you beat the game normally, but you can still fly your Arwing through them! Then at the end, you can shoot the letters of "THE END"
(while being attacked by enemy planes!) to make then fly up and flip around in the air. You don't get anything extra, but it's fun! If you die, you start at the beginning of the level ("Out of this Dimension")
Double Wing Blasters
To get the double wing blasters, follow Slippy through all the loops on the first level of any route. Good luck!
When the game ends and the Air-wing is spinning around, press Y on Controller Two to select an enemy. You can now rotate and zoom in and out just like you could with the Air-wing.
