Zelda A Link to the Past - Trinexx - Speed kill

Trinexx beaten in 25 seconds. Played in real time on Snes9x v1.43 rerecording.

Note that the Golden Sword (Lv.4) is required to beat it this fast, though the tricks still work even if you don't have it.

The first trick to killing Trinexx fast is getting behind it. (Don't worry, its tail won't hurt you.) Using the Ice Rod, you can shoot and stun the fire head from behind, before it would otherwise be vulnerable, then slash it with your sword. After that you can take out the ice head normally.

The second trick is that Trinexx's main head is vulnerable to your sword from the time it starts moving out of its exploding shell to the time its central body section starts flashing. If you stand at just the right angle, you can hit it twice with a spin attack as it's coming out, then slash it once more to kill it.
