Brazilian versionThe Brazilian version of Phantasy Star III is known for its bad translation, with some weird portions of text. But even weirder is the bug that happens if you use the ESCAPIPE trick at the start of the game (see Hidden message trivia section on how to perform this). The king will tell you something totally nonsense, and so will the guards (usually they would say nothing). It seems that what they speak are portions of text that would appear further in the game.
Hidden messageThere is a hidden message in Phantasy Star III Start a new game. Un-equip Rhys, and sell his gear to the TOOL shop. Then purchase a ESCAPIPE. Enter the castle, as you normally would. When Rhys is taken to the dungeon. Use the ESCAPIPE. And talk to the King.
