Dark Cloud 2 (PS2/PCSX2) Glitch - Chapter 5 Boss Without Fire Horn

A glitch that lets you fight Monster Gaspard before getting the Fire Horn. Part of the left invisible wall for some reason allows Max to hover up it with specific running angles, speed, and camera angles. I have looked all over the game for more invisible walls that do this, but I&only found a few that allow going out of bounds. If anyone finds another location where this works, please let me know.
