Final Fantasy I & II: Dawn of Souls Cheats

Okay, once you get the toad spell to level 16, get on the snowship, then hold A and press the B button 22 times. The secret minigame will then pop up. Play the first one, but don't worry about winning. After you uncover all the toad squares, write the pattern down. Some look a lot alike, so be careful. After that, start a game and give up 31 times without playing. On the 32nd time, it will be the same exact pattern as the one you wrote down. You can now get the best sword and armor in the game.

To do extra damage, take any damage doing spell(such as Fire, Ice or Holy)
Now go into a fight with only one monster and when your aiming your spell hit up to target every monster (even though there's just one) and attack. you do 1.5 more damage then if you attacked with it aimed only for the solo monster, because the way this damage is done is (Spell damage)x 1.5/ by the number of monsters

You still get the 1.5 boast to the spell, but it is divided by 1, thus not lowering its damage compared to if there were 2 monsters.
