Luigi's Mansion Cheats

OK when you go into the telephone room when the lights are out the professer will call and say there is a gost that likes to stay in dark places and a room that is filled with mirrors.Uncle Grimmly is the gost your looking for and he will be in the wardrobe room up stairs. When you get there make sure luigi is saring at you and the uncle grimmly will show up. When he raises his arms and makes a noise thats when you see his heart and then you suck him up. Sorry this a long descrition to read but many people have a problem with this guy. Hope this helps ^.^.

In several rooms, you may notice that there is a mirror there. If you search a mirror with the GameBoy Horror, you'll be warped back to the 1F Foyer. Note that this does not work with the mirror in the Mirror Room, though.

Complete the game 15 times and go to options, there is the settings where you can go try out GOD Mode.

Light all of the candles in the fortune tellers room to get it

Once you are able to go to the garden or yard in the backyard, go down the well and keep walking towards the right side. Then blah blah blah happens. Then come back to the well later but don't go in it just wait and stand outside of it. Don't move and stay very quiet. You will hear Mario say, Luigi, what is taking so long?" or something like that!

Go through the the storyline without collecting ANY piece of money. (Even a coin!) The only piece of money you can collect is King Boo's crown. You'll tell you have the H-rank Mansion when at the end you'll see a tent instead of you're own mansion! It's hilarious! (poor luigi)

Hold B + X and Start for 2 seconds

Enter this one hallway in level 1 where you'll find your first 3
gallery ghosts to capture. The firsts one's Neville. Look the other
way behind the rocking chair to see Neville reading a book. Avoid the
flying books and wait till Neville yawns. That's your cue to shine the
light on him and suck him in!

First gold diamond: Given to you when you catch Boo number 50.
Second gold diamond: After you fight the dog outside the mansion, water the seed under the balcony. It will sprout. Return after going to the next area, water it again, and it will grow again. Return again after beating the Giant Boo on the balcony, and water it again. It will spit out a lot of bills, coins, and finally a gold diamond.

1. Mr. Luggs: suck up some of his ghostly food after you light the candles with your fire elemental. Some normal ghosts will appear. Suck those up. After you do that, suck up the rest of his food. He will shoot fireballs at you. Dodge them until he gets tired of belching fireballs at you...
If you need any help whatsoever, I beat the whole game twice in a week and a half.
