Instead of trying to catch the key by running to that specific spot all the time let the key drop. Then after it has dropped, hold on to up and jump on top of it and it will say "Nice catch".

At the end of each stage you can grab the key and receive a bonus 5,000 points. Have the key on your left side, stand close to it, and jump towards the left. It takes a bit of practice to get the timing down. If you get the key as you begin your jump you should see the message "Nice Catch!" and receive 5,000 extra points.

Enable Invincibility and choose level 5. Pass the three Minstral Winds and the Cyclops on the wall, climb the ladders, and stand on the highest block. Walk to the edge facing the pit, turn around, and walk to the other end of the block. The game should automatically reset (if it doesn't, repeat the back and forth walking). Repeat the invincibility code, choose level 5 again, and repeat the pacing on the wall until the game resets again. Press START at the Title screen, and notice how strange ...

Wait for the "Start" message, then push A, A, A, A, UP, DOWN, LEFT, RIGHT. You should hear a chime. Then press and hold B, then START. You should hear another chime. Finally, press and hold C, then push START.

From the Options screen, select 26 for music and 56 for sound. Then hold DOWN-LEFT + A + B + C + START.

To go to any level in the game, press Up, Down, Left, Right at the title screen. Repeat until you hear a tone. Then use the following codes to choose a level. Press A to go to the second half of a level.
