Save Anytime on Majora's Mask
On Majora's Mask you can make a save anytime! You need both files open for this or it won't work. Simply save the game at an owl statue like normal, then when the game exits, go to the file select and copy the file you just saved to Save 2, then you can continue the game without having to worry about the game freezing (making you lose all your progress) and you can get a good save at any time.
