Level 8-4 tips

Level 8-4 can be kind of confusing, and down right frustrating after a while. Here's a little help... the pipes that you should go down always follow a lava hazard. First keep going until you see lava, then go across it using the mover, and go down the next pipe. When you come up go to the right (as if you have a choice). After a small lava pool there are 2 winged turtles and a pipe in the air. Kill the turtles and to the left of the pipe, about 2 spaces over, is a hidden block. Hit it, then go down the pipe. When you come up go to the right again, look out for the flying fish, and go down the pipe after the small lava hazard. This should bring you to an underwater world. Go through that world, and the pipe at the end. When you come up you should see a hammer brother, the next enemy after that is the last one. Get the axe, save the princess, and start all over again.

Warp to World 6, 7, or 8

To get to warp to World 6, 7, or 8, go to World 4-2 and go through the level until you find the ? blocks. Jump over the pit and move to the square under the last block above. Jump, and a secret block will appear. Jump on top, break the block above, and the one to the left of it. Fall to the left, and jump. Another secret block will appear. Jump on that, hit your head on the one and break the first block. A beanstalk will go up! Climb it and go through the level. Then there will be warp zone to Level 6, 7 and 8.

Secret World

Go to the end of World 1-2 where you make the decision to jump up to the warp or go to 1-3. There you move over to where it shows just the pipe and the blocks on top. Then you hit each block out that you can, until just the 2 farthest to the right are there, then you get on the left edge of the pipe, face left, duck and jump to the right into the wall. If your luckly, you may go through the wall. Go in the pipe to the left. If that won't work, face left, on the left edge of the pipe, and while standing, jump to the right into the wall to the right. This will take you to the famous World -1 level that never ends.

Warp to World 5

After you do the trick at the end of World 1-2 that lets you float through the wall (see Ben Brand's tip, above this tip), instead of going into the 1st pipe on the left and entering the minus world, go into the middle pipe. This will warp you straight to World 5-1!!! If you go into the pipe on the right, it will also take you to the -1 world. Don't move too far to the right, though, or everything will turn into the regular warp zone again.

99 lives

Go to Level 3-1 almost to the end where there's a big row of stairs with two turtles on it. Let the first one fall and then go to the second and wait for it to be barely off the edge. Jump on it and keep jumping on it to get 99 lives. Don't get more then 99 lives or you might get a Game Over.

Be small and have Fire power

I haven't gotten this trick to work yet in Super Mario All-Stars, so it may have been taken out, but it does work in the original NES version. The only level I've gotten it to work on, is Level 2-4, but I think it works in others too.. Here's what you do. First, you need to get to Bowser with either Big Mario or Fire Mario. Now, this is the tricky part. You have to hit the axe (while still in the big form) AND Bowser at the SAME time (trust me, it's possible). This will cause you to shrink down, and Bowser will fall into the lava. Now, In world 3-1 (or which ever world comes next, if you do it in a level other than 2-4), and get the first Mushroom. You will grow big for a second, and then shrink again. Now, go to the next item block (it's important that you don't get hit), and hit it. A Fire Flower will pop up. When you get it, you will still be small, but every time you shoot a fireball, Mario will grow big for a brief instant to shoot it, and shrink again. This trick wares off once you get hit. I'm not sure if it's still there if you beat the level, since I never could without getting hit once, but it might.

This trick also works somewhat when you are small Mario at Bowser, but it produces different effects. What happens, is when you hit the axe and Bowser at the same time when you're small, Mario will do his little Death Scene, but he floats at an angle into the area where the Mushroom guy is and falls through the floor next to him. I'm not sure if you lose a life or not, but I don't think that it causes any other effects other than Mario dyeing in the Mushroom Guy's room.

Fireworks

Catch the flagpole at the end of the stage when the last digit of the timer is a 1, 3, or 6. One, three, or six bursts of fireworks will go off, giving you 500 points for each.

Continue

When your game is over, hold A and press Start on the Title screen. This lets you continue from the beginning of the world that you were defeated in.

More secret worlds

Through the use of an emulator (like FCE Ultra) and a level editor (like SMB Utility), I have been able to find three more 'Minus Worlds'.

Make sure to back up your ROM first.

First, edit world 2-2 with a flag in the water, changing 1-2 so you can get to the Minus World more easily, and altering 3-4 with another premature flag.

Then, fire up your emulator (I prefer NESten or FCE Ultra) and load your modified SMB.

World 1-1:
Just play through this one as if nothing had changed.

World 1-2:
Get to the end, but instead of using the pipe, take your modified path to the Minus World. Enter the glitched zone.

World -1:
The famous endless water level. Keep going until you see your submerged flag. Get the flag.

World -2:
This is just like world 3-4, but underwater. Look for your other flag, and take it.

World -3:
Again based on 3-4, this baby has an 'overworld' theme to it. You can see a buncha enemies crawling up above the ceiling. Now again, take your flag.

World -4:
Now, this is just a barren underground level. You are stuck at the top (you're supposed to fall down to the ground, but the ceiling bars your path) and you can't move. The only way out is to reset the game.
