Bonus Dungeon Location - Once you have collected all the legendary weapons and beaten the game load your cleared game save and head towards Phantom Village. Just south of there you will see bubbles on the water use your sub to dive under the bubbles and you will see the entry to the bonus dungeon.

Easy Walse Castle Basement Looting - This works only on the Gameboy Advance version of Final Fantasy V. After so many steps, you are automatically thrust into battle. However, if you quicksave, exit and continue, the step counter is reset. If you take only 5 steps, a few more if you're feeling risky, save and load, you can get all the treasures and get out without encountering a single Jackanapes. Like this, you don't have to run if you are going for the Brave Blade and you do not have to encounter the Jackanapes on your first visit to the castle.

Music Player - Beat the game once, then the music player will be available in Extra at the main menu.

No forced runs from Chicken Knife - The weapon Chicken Knife has a "special" ability to force the user to run away from battle every now and then. But, there is a way to trick the game into NOT activating this effect while still using this powerful weapon.

1. You must be a Ninja, Thief with Dual-Wield, OR Freelancer with Dual-Wield.
2. Equip the weapon Twin Lance in your right hand. (Twin Lance is a Ninja/Thief exclusive weapon)
3. Equip the weapon Chicken Knife in your left hand.

Because Twin Lance has the inherent ability to attack twice, you will be attacking a total of three times with this setup. However, the game is tricked into thinking that all the attacks have already been performed, so it does NOT check the Chicken Knife's special ability when it is the third attack. Remember, Twin Lance must be in your RIGHT hand, not left hand, or this will not work.
