No, thats like a hack/ glitch thing isn't it?
Yes, you can dual wielding. But only if the end of this game...
uhhh... but the guy said you can use duel wielding in mission mode without a hack, that he was unlockable
yes it is possible. the way to do it is simple; just finish the game, save it go to moogle shop and (it is not synthesize! it is buying with heart points) buy the key blade which costs 30000 heart points. after that in it's link put 3 ability unit and you will have dual-wield roxas at mission mode. the only time you can use dual-wield roxas is after you beat xion.
P.S: actually i wanted to put it into a spolier, but i don't know how. if it spoiled anyone, i apologize.
