Unlock Endings
When you have a game completion time of 3-5 hours you will get the normal ending of Samus standing still. If you take longer than 5 hours to complete the game you will get the bad ending which will have Samus running in place. If you manage to complete the game in under 3 hours you get the ending with Samus in her bikini.
