I want to see a hack for A Link to the Past that turns into Ocarina of Time for the SNES. The flute would get replaced with the Ocarina, complete with the ability to.play the songs by using the D-Pad and A button. The Day/Night patch would be added, with the additions that the music fades away at night, and the Sun Song plays at sunrise. The Sun Song makes the time skip foward twelve hours, and playing the Song of Storms (My favorite melody in OoT) makes it rain for thirty seconds.
The Great Fairies are in the game, and give you special abilities as well as healing you, but you have to play Zelda's Lullaby in front of the fountain first. The Red Shield would get replaced with the Hylian Shield, but Child Link can only have it on his back, making it so that facing away from enemies deflects their attacks. Getting the Master Sword makes the game go to the future, So yuo can then use the Tunics and other things.
The water in the game would have a sort of feeling of depth to it, and pressing A while swimming allows you to dive down, helpful for avoiding enemies and collecting underwater items. The boots make you sink down to the very bottom, so you can get to the Water Temple (*Shudder*) and get other things, too. Even the Hover Boots would be added, with the loss of friction but the ability to temporarily hover.
The item system would be made to reduce pausing. You could equip an item to each direction of the D-pad by highlighting the item, the pressing L (or R) and the direction you want the item to be asigned to. Pressing L or R in-game makes it pause for a second, and the game shows the items currently equipped. If you had the Slingshot saved to up, pressing L+up would make it the current item.
The Pause Menu stores the tunics, swords, and boots. it also shows the Melodies you learned so far. If you for some reason forget one of them, you can select it in the Menu to have it tell you how to play it. Also, the scarecrows would be at Lake Hylia, and you would have a large amount of freedom to play the Ocarina to make a song for them, even being able to make harmonies and such. You can then save it and even choose to have it play in the place of some BGM.
Anyways, I think that's about it. I have lots of ideas, so I post in idea threads a decent amount.
