FF3j water cave

I'm having some trouble finding my way in the water cave off the floating continent in FF3j. I'm in room b3f and I can't seem to figure out where to go. If I follow the path above the water I reach a dead end, and I can't seem to get into the water to reach the area below. Does anyone know what I'm doing wrong?

Another ROM glitch. Again, no idea how to fix it.

if it persists to with that glitch, just try and find another ff3j rom, as long as it's used on the same emulator your save should work.
