In final fantasy 3 for the DS, will the game file start you back at the beginning if you beat the final boss?

I have the ability to beat the final boss easily, but I'm worried that I won't get to keep the saved game and I want to fight (and beat) the iron giant boss. Also tips for training and killing the giant would be nice!In final fantasy 3 for the DS, will the game file start you back at the beginning if you beat the final boss?The game is not like GTA...you'll go back to the beginning after beating the last boss...Go do everything, sidequests etc. then beat the hell out of the last boss...In final fantasy 3 for the DS, will the game file start you back at the beginning if you beat the final boss?well of course not what game does that these days? the original final fantasy games way back used to just start in the beginning.. but most likely after you beat the final boss, youll be outside the crystal tower or something.
