Sorry for the lack of update, I tried it out on GCN NTSC and had similar results to Torp, fell through a few times in an hour and couldn't get to the corridor. Here's a clip of it working:

I also tried it on PS2 for fun but the hitboxes on the rocks seem to be larger and you can't even get in between them like you can in GCN.

Insane find!! I'm going to test it out on GameCube NTSC tonight

The 3DSVC has a different bios. So, the intro is different (No GameBoy Screen) and the manips won't work.
