The requirements to reach the Thunderhead in BiT have been decreased!
To reach the Thunderhead in BiT, the main idea has always been to use the Groosenator launch. Groose naturally suggest launching you to Bug Heaven after either having 3 Song of the Hero parts or after beating Demise on Hero Mode, and this is what we thought was necessary.
It turns out where Groose sends you depends on what we call "zone flags". With a specific zone flag (we call it 1x04), we can force him to send us to Bug Heaven instead of the destination we asked him. This doesn't seem to change anything, but actually there is one launch that's a bit special: the Flooded Faron Woods launch. Now, it is possible to ask Groose to launch us to Flooded Faron but then hijack the zone flag using BiT. This allows us to reach the Thunderhead in BiT with the only requirement being having access to Flooded Faron Woods (which is still a heavy requirement, but a different one from earlier).
Zone flag 1x04, specifically, needs to be in room 1. The only place we currently know that has this flag is Skyview Temple: talk to the Stone Tablet in the 2nd room then save at the statue. That file also needs scene flag 9x80, are else the Groosenator simply doesn't work (this scene flag is a groosenator requirement).
Possibilities for the future:
- room 1 zone flag 1x80 would allow early lanayru BiT, unfortunately we don't know where we can get this flag.
- room 1 zone flag 1x01 might allow early flooded faron woods using the groosenator to lanayru. This would skip the Imprisoned 3 fight in a category like 100% (although idk if that would be faster to setup). But the problem is the same: we can't save this flag anywhere so far.
