Zelda 3 A Link to the Past Walkthrough on Super NES: Eastern Palace (1st Medallion) (GBA, SNES, Super Nintendo)

Lift the middle pot and step on the switch. Go through the door, press the button in the middle of the bridge and go through the other door. Go down the stairs, go up avoiding the balls, go up the stairs (if you go left before, you'll find a chest with 100 rupees) and take the door. At the intersection in image 1, turn right, then right again through the top door. Press the button under the middle pot and take the door. Open the chest: you find the Compass. Go back to the intersection and go left.

Kill all the enemies in the room to get a key (3) and open the door. Go through the dark room and go right to find the Map. Go back to the left and open the door with the key. Cross the bridge and go down one floor. Go all the way to the right (1) to find a chest with the Big Key. Go back a little, climb the stairs and open the big chest containing the Bow (2). Enter the big door at the top of the room. Go right, then up (3) and open the door.

Press the button under the top right pot (1) to open the door. Go through the rooms and defeat the enemies to get keys if necessary. Use the bow to kill the cyclops enemies (2) and the statues that throw balls (shoot an arrow on the open eye - image 3 above). You finally arrive at the boss door. You can kill the boss, either by hitting with your sword (long) (2), or with arrows (3 per guy, much faster but less sporty!). You get a new heart as well as a medallion (3).

Congratulations! You have recovered the first medallion. Now go back to see Sahasrahla who will have something to give you.
