Is it possible to activate this no-clip hack/cheat on TLOZ:OOT Master Quest?

Hey everyone, I saw this gameplay footage of Zelda Ocarina of Time Master Quest the other day, and I was wondering if it's possible to do this no-clip like hack that can be seen at 8:52 (if you watch the video you can see it multiple more times) using Project64 and a keyboard?
The title of the video is "Playing with early Ocarina of Time Beta Maps" and it was uploaded by ZFG. (sorry i can't post URLs)

Looks like debug tools, you would need a debug build of the game.

Thank you very much for your answer! I enabled debug mode in my emulator, and although i'm not sure if it changed anything, i figured out how to fly with keyboard! So to everyone who struggle with it like i did, here's how you can do it:

Press L (which is A on the keyboard) and Right on the DPad (which is either L or 6 on the NumPad, depends on what version you're using i think) at the same time, which activates this flying mode.
You can move around horizontally with the Dpad. To go upwards, press A (X), to go downwards press B (C). To go faster press R (S) while moving.
Press L and DPad Right again to get out of flying mode.

If it doesn't work, check the controller settings to find out which buttons activate the other, it may be different for some people.
