Not sure if anyone has found this yet. So in the ocarina of time debug rom I stumbled across an alternative spirit temple dungeon oddly hidden. No one has seemed to come across it yet. I have looked quite far and wide for any findings.
It is found via level version selection (using L or R buttons) WHen selecting the third from final level on the german version. (I didnt have the english patch) Called:
222 : jjjjfnjznv
Then proceeding to alter the rvbff : "J" (probably level alteration selection)
changing it from the japanese characters that are shown as default, to:
X2:
(Be sure you have selected older link at this point)
Causes you to spawn inside the giant statues face where the boss door is located in the spirit temple.
I find this fairly odd because the face is not broken yet and there are major alterations to the main layout of the temple. Such as floating time blocks, weird yellow eye switch locations. Pillars with torches.
From there if you continue to solve the puzzles it just gets weirder.
I have been able to complete several before my emulator crashed. I will work on getting farther.
In the mean time. Be aware that when this level is started there is approximately a 1/10 percent chance it will not load correctly or the screen will freeze up. Well.... for me anyway.
Please report any findings you may have seen or if someone is also aware of this odd dungeon layout.
