Hints: 

Unlimited gold - When you get the Chief Fisherman's' Daughter, go to the beach where she goes to find the Aquamarine. When you fight the little Jewel Leapers. they give you the stones that are needed to make Runes. Get a large number of them and some gold, then go to the 
Rune-Makers shop. You will want to Refine those Gems into Runes, which cost 230 gold. When they are refined, the Rune Shop will buy them back at 400 to 500 gold. 

Extra items:-  When the game first starts and you are in the castle, go to where you get the Small Lithograph and the Fire Rune. Go to the bridge where you came from and fight all the enemies. Next, go back into the place where you get the Small Lithograph and Fire Rune then exit. Keep repeating this and you will get all sorts of stock, mainly Medicines and Red Stones. You also will get experience points that make you stronger. To get even more items, when you fight use the Counter Guard. You will get Tactical Bonuses and more items.
