FF 1 Strategic Masters

[Vincent, Thunder God]

Hi, I was wondering, has anyone ever beaten FF 1 with an all-mage party or a 1-person party (you keep all but 1 character KOed)? They are two fairly well-known challenges that people take with the game. It's one thing to beat either challenge on Easy in FF origins...how about beating the game on Normal? Or on the NES with no memo saves?

If you didn't do those two, what was the trickiest party you ever used?
