Back in Time (BiT) is a glitch that exists in Skyward Sword, Twilight Princess, and Wind Waker. It allows you to retain control of Link while on the title screen. Each of these games activate BiT differently, with very different behaviors and uses.
To activate BiT, first die. Some useful methods of dying:
Then on the continue prompt, choose continue and reset the game immediately afterwards. You have about a half-second window in which to reset, and you can reset the game with either the Reset button on the Wii or the Reset option in the Home Menu.
If done correctly the title screen will show and Link will spawn in mid-air and fall into a void. He is then dropped back on solid ground by a non-existing Skyloft Knight, and a glitched cutscene will play. You should then gain control of Link, and be able to move around Skyloft.
If the title screen loads normally, then you likely reset before selecting continue. If the game turns black and freezes, then you reset the game too late.
When you start the Back in Time Glitch (BiT), a different version of Skyloft is loaded. Performing a BiTSave will load you in this alternate version of Skyloft as well.
This version of Skyloft has some key differences from the regular Skyloft:
There are a number of bizarre things that can happen during BiT, many of which will crash the game.
There are several useful glitches that employ Back in Time. The four major tricks have their own pages:
Two smaller glitches in BiT that are nonetheless useful are below.
While in BiT, start deleting a file. While the file is still deleting, save at a statue. After the game is done deleting and saving, the file will appear to have one heart, and the name will be a blurred mark. When the file is loaded, Link instantly dies. This is useful for activating BiT easily when Bombs or other damage sources are not an option.
The corrupt file is currently only used in NTSC v1.0 speedruns and in Harp speedruns; for Japanese speedruns it is faster to skip the Corrupt File.
BiTMagic is a method of opening the upper and lower academy gates in BiT. To do this, you must have a saved file with the following properties:
If you copy a file with these properties into slot 3, then when you next enter BiT, both gates will be open. If you have this file in a different slot, then you can open the gates in BiT by selecting that file.
In Harp speedruns, when performing the Sailcloth Skip, it is possible to open the Academy Gates by bonking the tree near the bazaar. By copying File 1 to File 3 at the beginning of this BiT, you can then do this for the remaining BiTWarps that use the Upper Academy Statue, saving time.
Again, this is only useful during Harp speedruns, as full game runs cannot skip the Sailcloth and would use the normal version of BiTMagic instead.
While the Back In Time Glitch (BiT) is active, it is possible to load items and other information from the other save files by performing a number of actions.
In all cases, the file that the information is loaded from whichever file you have selected when the action occurs. If you haven't selected a file, it will use file 3. If file 3 is empty, it will use file 2, and if that file is empty, it will pick file 1. If all of the files are empty, it will use a BiT file.
Note that some of this documentation may be inaccurate.
Whenever you select a file in the file menu, some things change on your BiT file.
The rupee effects doesn't occur until your rupee count changes or you perform the items/loading zone/chest methods.
When you save over a file during BiT, you will transfer different things from that file.
Note: To unlock Fi using the Saving method, you have to combine it with the item method.
Picking up a Stamina Fruit, Heart, Rupee, or other item with a text box updates the following information:
Entering a loading zone updates the following information:
Starting a cutscene will update the following information:
Opening a chest will update the following information:
When you save, a saving flag is set. If you try to reset the game while the saving flag is set, then all audio is removed and your buttons no longer work. The game will reset once the saving flag is removed. This is done to prevent save corruption by turning off the Wii while saving.
While in BiT, load a file, and save right before the screen fully fades to black. If done right, the saving message should not appear. What will happen is that the saving flag is set, but no save is done, and your file is loaded normally and can be played normal. You will know that the save flag is set if you cannot press the Home button.
When the saving flag is set, attempting to reset the game will result in the Saving Flag glitch. Audio is removed and buttons do not work. You can still use the control stick (to move Link) and use Motion+ (to slash your sword). You can still enter loading zones, and areas are loaded as normal, but the Saving Flag glitch is still in effect. All triggers work normally.
Anything that requires button input is impossible, such as progressing through text and saving. This makes this glitch nearly useless.
Note: Saving at a statue will set the saving flag again, and then remove it when the save is complete, which fixes the saving flag glitch.
These are some loading glitches that allow you to load your file in BiT in unusual ways.
While in BiT, open a door and load a file at the same time. Your file will be loaded in the Area that the door led to.
Loading zones and beds are a little harder, but they are the exact same concept as with the doors. Enter a loading zone, such as to the Goddess Statue or the Waterfall Cave. Load your file as the screen starts to fade to black. BiT should end and the file will load in the Area you were entering.
If you die during BiT and then choose continue and load at the same time, the file you loaded will warp to the respawn location that was set during BiT. BiT is ended.
If no respawn location has been set (i.e. you died with out entering an new Area during BiT), you'll freeze and get a black screen.
