Get Jess' Armor fixed at no cost

Instead of going to Lurvy to fix the armor, climb the cliffs behind his house until you are the highest you can go on the right side. From there, jump down a few cliffs to the treasure chest on the cliff directly behind Lurvy's house. And from that cliff jump to his roof and then on top of his chimney, you will fall into Lurvy's house. You catch Lurvy doing something and he says that he'll fix anything of yours for free, if you don't tell anyone about his secret.

Legendary Sword

To get the Legend Sword (most powerful weapon in the game) you must have the "POWER GLOVE" given to you by Jess. Then you need to die and use the "QUICK RESTART" feature over 16 times (this can be done at any time in the game even before you get the power glove.) After doing all of that head for the statue of King Snow which is east of Inoa Village and use the power glove to lift the large rock blocking your way to the staue. Walk up to the statue and the screen darkens, if you have done all of the above correctly King Snow will pity you and give you the Legend Sword. This Sword should be your weapon of choice, although it cannot perform a charge attack it is still the strongest weapon in the entire game.
