If you are talking about Wind Waker, then you go to tingle on tingle island, and pay something around 584 rupees...for just one map.
You have to bring the charts to Tingle Island to get them deciphered.
You will need to find the 8 Triforce charts. Be using the Incredible chart, it will tell you where each chart is located. After you collect and decipher a triforce chart, you can check it or the incredible chart to find the location of the Triforce Shard. You will then have to sail, or teleport and salvage the chest with the grappling hook.
It is just off of the dock, but if you have the TRIFORCE CHART, the area that the triforce peice is will be lit up when you open the treasure chart.
#1 you dont get the triforce chart from the ghostship, you get it from the big hole with the head covering it on outset island, search my posts, i discussed it in a previous post
to get the triforce chart first go to the far left hand side of the map on of those island has a chart on it in a cave then once you get it go to one of the islands on the map when the moon coressponds with that island then when you see it ram it
put the triforce simbol on that red door and the continue and find it
The last symbol is the triforce
You need to obtain Triforce Chart # 2 from the Private Oasis first. Then use the grappling hook like finding any other treasure in the Great Ocean.
this may mean a series of things,so I'll list all i can think of. 1. talk to the merman, (the fishies that jump out of the water at every square, give them bait and they'll give info on that island including a drawing on it to add to your main sea chart) 2. collect treasure charts. they are located in all sorts of places in the game, get the guide or go to a Zelda website if you really want to get all of them. 3. go to your sea chart and press the Y button to open up your list of treasure charts. you can go through them this way and see all the ones you've collected. hope this helped and have fun.
Tingle charges 398 ruppees to translate a triforce chart so save up about 3190 for him to read all of them
The cabana deed lets you go into the private oasis. It is loacted south of the tower of the gods. You show the deed to the door and you can go in. To get the cabana deed, you need to show the teacher on windfall island 20 Joy pendants. Inside the caban, is a triforce chart. To get the triforce chart, use the grapple hook to the hook on the ceiling, which will stop the fire and you can go in the hole. Explore around in there, then you'll find the two tiles on the floor. Use the Wind's Reqiuem (up, left, right) to make a treasure chest appear, which has the triforce chart.
1. there are several triforce shards, so not 1 but 8. 2. the shards aren't on any island, the CHARTS are on islands, wich 2 of them are actually a gunship and a ghost ship. 3. Go get the IN-credible Chart from your postbox. Fairy on the north fairy isle gives you a bigger wallet so you can afford its price. wich is 201 rupees. On the chart are the locations of all triforce charts. oh, and free Tingle from his prison in windfall before anything.
