How do you get unlimited money in Resident Evil 4 for gamecube

There are no cheats for the game, you can keep all your money/weapons and items after completing the game though, when you start a new game with the "Cleared game" feature. You can also get extra money by shooting all the animals like crows and fish, also in the Castle after you get out of the sewer you will appear at the top of a large ball room were there are some monks doing a sacrifice. If you alert them they all run away but if you throw a grenade down every single person you kill will drop a spinel or a los illuminados pendent.
