BS The Legend of Zelda: Inishie no Sekiban/Week 4/Dungeon 7

First of all, light the torches (the top-left pot has a Full Refill) and go through the door. Grab the key and open the chest for the Map.

Go back, head to the left. Open the chest for the Compass. Go through the door.

Go up and open the chest for 100 rupees--and look, some holes appeared...!

Go down, pull the tongue, and go through the door. Bomb the wall, and go thru.

Open the chests (100 rupees), pull the tongue, and go through the door. For a massive 400 rupees the upgrade thief will give you more bombs. Go back and down the stairs to B3. Go down the right-hand stairs.

Kill all the enemies here and go through the left-hand door.

Go up and through the right-hand door. Open the chest for the Big Key and go back left. Open the chest for a small key, open the door, and go up the stairs.

Open the Big Chest (if you wish; the game is broken, this item's not necessary) for the Cane of Somaria. Open the small chest to get the Glove, and go through the top-right Boss door. Bottle the Fairies and collect the goodies if needed.

Healed up and topped up? Good. Walk to the left until the screen scrolls, and you will find yourself in the Boss Room. :)

Again, you can scroll surprisingly far vertically, but not much horizontally. Again, this boss can run out of the reachable area, forcing you to leave the room and start over :( ...therefore when fighting him (or it?) try to hit the bits from directions such as they'll recoil back into the centre of the room, even if it means taking additional damage.

Collect the Heart Container and Tablet and head out!
