Maximo Vs Army of Zin Cheats (PlayStation 2)

It's very simple. On the very first board of the game, you begin 
  standing in front of the town sign. just jump up an smash the sign 
  with your sword and it will rain money. (maybe $50 plus or minus) 
  simply save your game, and quit. the system will automatically reset 
  the first board like you were never there. jump up and smash the sign 
  again, save again, start over again ect....  

 

 

On Level 9, Down with the Ship, you have three minutes to destroy six reactors.
Using the Drill Attack, you can destroy a reactor with three hits. Destroy five reactors,
then spend the rest of your time fighting enemies. You can earn lots of money destroying
enemies. When time is almost up, destroy the final reactor. Go back to Level 2. Purchase
power-ups and continues from the merchant then save and quit the game. Load your save,
return to Level 9 and repeat the tactic. You can do this as many times as you like and
earn oodles of cash in the process.

If you would like to Master every stage, you will have to do the following: save 

all of the lives of the Innocents, find every one of the buried Treasure Chests 

(Secret Chests), collect every item in the stage (Koins, Diamonds, Armor... 

Everything, basically), and defeat every enemy in the stage (including those 

Evil Bunnies.) If an enemy falls off of the stage, it is counted as a kill. If 

you collect an item and die, you will have still collected the item. You will be 

rewarded with Art Galleries of concept images.
