Bonus Dungeon Location:
-----------------------

Easy Walse Castle Basement Looting Glitch:
------------------------------------------
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.
