Branch 0 contains finished run.
Branch 2 and 3 prevent crashing after item glitch, but the cave to 9th level isn't opened.
The item glitch is achieved by executing 6C 9A B3 in Link's and Enemy 1 and 2's Y positions.
This is based on RAT's movie.
It shows that it is possible to warp glitch all throught level 9, using the sidewards wooden sword do a different scrolling than the red bombs.
