I've read a lot of rumors, but none work..
Entering gogo's area with 1 person lalala
256 fights on after ruin starting island..

Wondering if there is any real secrets on the american consol snes cartrage that work?

guess no? just MMo'ers on this page? no old school FF players?

This sub-forum kinda died after the release of FFXIV:ARR and has turned into a big gold trade.

As for your question, I can sum it up quick.
I would call these characters "secret", or missable. Mog, Shadow, Gogo, Umaru and Gau.

Mog, Gau and Shadow must be recruited before World of Ruin.

I would really suggest that you check out a walktrough, to make it easier for yourself, or if you want, I can sum it up real quick.

As for the 256 fights you mentioned. After getting Locke back in the party in the World of Ruin you can pick up the cursed shield from a house in Narche. You need to equip the Cursed shield and do the 256 battles with it to get the Paladin shield (The best, or one of the best shields in the game.) As for the island, its probably the best place to do these battles, as the enemys there is so weak that they basicly kills them self.

Yeah I know all that I never had a problem getting 2x atma weapon, gogo, gau, umaro, mog, or shadow.. I also know that after you complete all his dream sequences you learn (no 100percent) that shade is edge from ff2 and is realms father or related..

Was wondering about ghestal (supposapbly gogo). And general leo.. Read lots of shit on the net, but its just that.. Shit

the only way to get leo in your party is via glitches which make your game mighty unstable
