Make Bomb Torizo wake up and close the grey door when you pick up the item PLM (of any kind, as long as it's index 1 in the room). Normally it wakes up whenever you have bombs collected, meaning the fight will trigger instantly if you already have bombs coming into the room, or the fight doesn't trigger at all if you change the item the chozo holds.

Includes a line you can uncomment to change the door close timer.

Patch with xkas, e.g.:
xkas "bomb torizo.asm" SM.smc
