Doh!
Sí, es verdad, esas caracteristicas solo estan en la versión de game boy (normal)....
En un FAQ he leido esto:
"The next boss battle can be extremely easy, or very difficult, depending on
your skill level. All you have to do is strike Moldorm's tail six times, but
every time you strike it, you fly backward. This wouldn't be a problem if it
weren't for the arena, which is nothing but a pit! So, you must strike the
boss at an angle where you will fly back, but not off the arena! A good
method is to get Moldorm's attention, then run in a circle around the center
pit. When you get close to Moldorm, strike its tail. Immediately reverse
direction, and then repeat the process. (NOTE: Don't worry about losing your
health in this battle. If you fall off, just revive yourself at the tower's
secret fairy fountain.) (NOTE: Falling off the arena means that you must
start the battle all over again. So, always be cautious about where you run.)"
Que resumido (y en castellano) viene a ser:
Tienes que darle 6 veces en la cola para eliminarlo. Para que no te tire al vacio, tienes que darle desde un angulo en el que cuando te lance, no caigas abajo. Un buen sistema es llamarle la atencion, dar una vuelta a su alrededor, y cuando te encuentres con su cola, dale con la espada. Entonces sigue dando vueltas pero hacia al otro lado, y así.
