"Another odd finding is that the glitch doesn’t seem to work with Falcon’s Up+B attack. I am not familiar enough with the mechanics of the game to understand why this might be the case."
I think this has something to do with the hammer hit in my previous post. It needs to be some kind of specific (grab-related) hitbox that freezes it, which CF's up+B lacks.
What exactly happens on frames 2-5 with Ganondorf?
On 'glitch frames': Ganon's status = 309, and Nana enters CaptureCaptain status. This is from the white text in dev-mode. There's not really much difference between a glitch frame and a non-glitch frame.
Do you need frame screenshots?
Hmm.
It seems the timing can change depending on Nana's position (or something else). Testing again in debug mode, the glitch is working on frames 2-4. Weird.
The frame advance function in Dev-mode is different from the emulator's frame advance function. I'm getting different results and different numbers from the white text. Even when advancing the same amount of frames. From dev-mode, it appears you can initiate the freeze glitch from a larger window. I was unable to do this earlier in the normal game.
I may need to restart the emulator or something as I'm getting inconsistent results. Needs more investigation.
