In the "hints" section someone tells you the real way to get Wario Karaoke. I'll tell you the cheat to get it. Go to the Sound Room. Put the little hand over the "Exit" sign. This is the hard part. With the hand on the "Exit" sign press Start, Select, Up on direction pad, L, and R at the SAME TIME. I recomend turning the gameboy sideways so that the side with start, select, and the direction pad are facing you. Press start and select both with your right thumb. Press Up with your left thumb. Press R with your left index finger and L with your left pinkie. It might take a few tries to get it down. When you do it right a sign saying karaoke will pop up next to the exit sign. Move the hand over it and press A to play it.
To beat Golden Diva you first need 10 tokkens for the item shop then chose the Black Dragon and go to that level. After the draogan fires the faces start to fly jump on top of one and pick it up and throw it up ito the open thing.After you throw all the faces you will have to throw items at the guut and after he shows his ugly face and slams the flor just hit him with an elbow bash. then hit the lip and youre done.
To unlock karaoke, get at least 10,000 coins or more on every level. Karaoke is located in the sound room. An easy way to get 10,000 coins is to collect the diamonds (worth 1,000 coins).
In any level, go to the scientist and Ground-pound him about 7 times. After, he will say, "Stop That, Please!".
In Wildflower Fields when you get to the big sunflower pick up a caterpillar and throw it at the center of the flower. The yellow in the center will decrease and you will get 500 coins.
Try to beat the bosses as fast as you can, because you want more treasure chests, because its pays off in the end of the video game.
This is easier than tearing paper! Just find a monkey and eat one of his apples. Stay where you are. Wario says: "Yeah, you!" When the monkey starts to throw another apple, he'll eat it instead!
Palm Tree Paradise: When you come to the second box with the jewel piece in it DON'T OPEN IT!!!!!! Jump on top of it. Then jump right into the wall. It's a secret place with a diamond there. If you accidently open the box dont worry. Go to the other side and there's a platform that you can go on to get to it.
Palm Tree Paradise: After you get the third C.D. walk right a screen and you'll reach a purple monster and some platforms you have to jump up. Jump up onto the first platform. Walk right through the wall. It's actually a secret place and there's a box there with the secret C.D. inside.
Palm Tree Paradise: After you get the final jewel piece you'll notice that there's a wall on your left. Walk through it. It's actually a secret place a there's a diamond there that's worth 1000 coins!
First go up to the monkey that throws berries. Go in front of the monkey and stand there untill it throws a berrie at you then you can become Fat Wario a when you jump the whole ground shakes.
When you are playing a mini game and you are about to lose, before it says GAME OVER, shut the gameboy off . Turn the gameboy on and you will still have you money, and you can keep playing until you win!!
