If you are playing the SNES/PS1 version...your battle is much harder. Here, Rosa's Curaja/Cure4 takes longer time to cast the spell. So what'll happen is this:

1. Big Bang will hurt your party by 2000 each almost every turn.
2. Rosa will try to cast Cure4 to heal, but at around level 65, Cure4 only heals the party for 1000 each. It also takes a long time to cast.
3. Zeromus will deal damage with Big Bang faster than Rosa can cure your party with Cure4, and you are screwed.

The only think I could think of doing is having Cecil and Kain, the ones who can survive Big Bang for more than two turns, attack and heal themselves with Elixers when their HP is low.

Fortunately, I don't think you are playing the SNES/PS1 version.
If you are playing the GBA version, just have Rosa keep on using Curaja on the party every turn she gets. Use it even Zeromus uses his next Big Bang; try to time it so that she'll heal the party immediately after Big Bang. Curaja/Cure4 is also faster in this game compared to the other two versions.
The effect of Dark Matter is not constant, that is, sometimes it'll reduce the damage of Big Bang, but other times it'll increase the damage.

I believe you mean that the PlayStation and GBA versions are harder than the SNES version...unless of course, it's the hardtype SNES version you were referring to.

Rosa casting Curaja every turn should be sufficient...it should be healing for more than just 1000 damage. If your party has full HP, wait until Big Bang hits to recover so that Rosa doesn't waste her MP on healing the party at full health.



Don't worry about Rydia dying, her poor HP ensures that she won't survive a Big Bang unless she's at a very high level. Zeromus will counterattack Bahamut with Flare, so Rydia isn't the most damage-dealing character in this battle.

As for the Reflect strategy, it is only really useful if you are attempting a low-level clear. If you're playing a normal game, there are far more damaging things that the party is capable of. Just have Edge throw all of your best weapons, Cain Jumping, Cecil attacking or using items (such as when Rosa's MP gets low), and Rosa casting Curaja on everyone every single turn, when the party is damaged. If Rydia somehow survives, try using her weaker summons other than Bahamut, unless you don't mind the Flare.
