how to use omega zero

how to use all powers

BEAT THE GAME WITH ALL SECRET DISK THEN AT THE START NEW GAME, HOLD L AND START THE
ADVENTURE WITH THE TRUE HERO

YOU CAN UNLOCK THE ULTIMATE MODE WHEN YOU ALREADY GOT ALL SECRET DISK AND BEAT THE
GAME.WHEN YOU START THE NEW GAME,PRESS R AND OMEGA WILL BE YOURS

Ultima mode is different from "Omega" mode,i saw in youtube,someone using omega form,it
has a different attack than ultima mode body.......

There is no Omega form, anway.

Just a hack, with this long combo that kills anything, but doesn't work with bosses.

But Ultimate Mode does exist. I have it. :D

but... i cant find some secret disk...(can tell me how to find all?)

I CANT FIGURE OUT HOW TO BECOME OMEGA ZERO HOW DO YOU DO IT
