Cheats for Lufia: The Legend Returns (GBC)
In every shop with a door behind the shopkeeper, you can go behind the building and get in through that door by pressing A. This allows you to get the items in the treasure chests. Also in Majari, if you enter through the back door, talk to the innkeeper and he will let you stay for free.
Buying new items in Ancient Cave
Go to the Ancient Cave. Every five or ten floors, you will meet an old man who sells items that are just in your price range. Exit his menu, then go back. He will have new items for sale based on your new income.
Gades Bracelet and Gades Blade
Defeat Gades the first time to get a Gades Bracelet, which boost your attack by 100 and defense by 200. This is very helpful throughout the game because it can be used in the Ancient Cave. If you defeat him a second time, you will get a Gades Blade. Note: You must be at least at level 20. This is very hard to obtain but will help in the long run.
Dragon Scale armor
Defeat the older Ancient (A.) Dragon, to get a Dragon Scale armor. This is an excellent armor for Wain. It is the best you can get in the game for awhile.
Delete saved game
Hold Start while powering on the Game Boy Color. Answer "Yes" at the prompt to delete your saved game data.
Easy level up
Answer the question from the green blob at the end of the Ancient Cave with "Nothing", then defeat the first enemy you meet outside. Your level will now be four to five times higher.
In most towns, the shopkeepers will sell you secret items if you go in through the back way.
