B8AC (Rising Lava After Getting Speedboots) [High] = 80 [Low] = 00
Sets the Rising Lava event, but can be used over and over. Basically, this PLM delays any rising lava effects (FX1) in a room unless it determines Samus has speedboots. If acquiring speedboots within the same room as the PLM, the lava will not rise until you return to the room.
