I have found out that those unlimited money glitches dont always work... and taking 15 gold pieces at a time can be a pain. So I found out that its easier to use the duplication cheat, not the one with the bows and arrows though, I've only got the on with just arrows to work.

Duplication Cheat:

Equip arrows, and punch the ground with attack, only with fists, then press B for the menu (before the punch is over).
Press A on the equipped arrows (a message will appear that arrows canot be unequipped), then drop the item you want to dupe, and if you have 50 arrows you will have 50 rings/whatever item free.

Note: This does not work everytime.

I would recommend finding a person to barter with, with at least 1000 gold. Then get a ring (becuase its light and you can hold alot with out being weighed down) and then you use the duplication cheat and then just sell the duped ones. But be careful, the number of arrows you use will be the number of duplications.. and it froze once when I had too many, I would recommend 50 arrows.
