Super Mario Advance 4: Super Mario Bros. 3 Cheats

After you beat the whole game, special coins at the beginning of the secret levels:
Levels and required coins:
1-4, 2-2, 3-8, 4-2, 5-5, 6-7, 7-2

Each will have a number on the bottom of the screen telling you how many coins in that level you need to get a white mushroom popup on the map. Once you achieve that many coins, the white mushroom house icon will show up.

If you manage to ''beat'' a spade house (by correctly matching the pieces into any of the 3 forms), you can unlock additional houses!

In addition, you can create different combos that can get you even more lives!

Heart house: Star is replaced with a racoon leaf, and matching it rewards you with 7 lives
Club House: Star/Leaf is replaces with the number ''3'', matching this awards you 9 lives
Diamond House: All items are replaced with stars..a Guarenteed win!

Once you have passed a diamond house, the cycle repeats itself.

To replay any level, fortress, and castle, beat every level in the game. Not just Bowser, every single level.

For each 150,000 points you get in Mario Brothers, a star will appear at the top of Mario Brothers at the game selection screen (where you pick between Super Mario Brothers 3 and Mario Brothers). You can get up to 5 stars maximum.
