How does the ship minigame work?
You must be on the ship (not the airship), hold A, and press B 55 times. (Replace A & B with X & Circle on the Playstation.) The object of this game is to get all the tiles into numerical order from left to right. On the NES version you get 100G for winning, and on the WSC/PSX/GBA you get the 100Gil and other stuff depending on how fast you are. On the WSC & PSX getting 1st gets you 10,000 Gil, 2nd gets you 5000, and 3rd gets you 2000. The GBA gives you various items for winning. (I have not had any luck getting this game to work on the MSX version.
