The first one I found is a salesperson selling some good items in the Castle of Tansicia. Go to the room with the bridge. You can already see him. Do this:

1. Go behind the bar.

2. You should be able to walk into a wall behind there.

3. Make your way around into the room.

4. You can still talk to the person while you're standing on the ground.

Note: This second one is completely pointless, even though it's fun.

Haven't you always wanted to work at a hotel? Here's your chance! Just do this!

1. Go to the inn at Matango.

2. Walk into the wall on the left side.

3. Make your way around to stand at the counter!

Once you have to have four of each type of healing item, you use them all one by one. When you're done you will have infanite life.

Get fired out of the cannon 50 time.

You can get the lv 9 sword without using the mana spell.

1. You need the lv 8 sword and Flammie.

2. Near the Ice Palace there will be a very small island next to it. Land on it.

3. If you go up and see neko when you land talk to him and save the game.

4. Hold L, R, start, select, for about 2 seconds, which will reset the game.

5. Start a new game and keep playing until you meet the 1st Mantis boss.

6. During the battle (not when they are talking and not after you win) hold L, R, start, select, for about two seconds again.

7. Select the game where you saved it at neko.

8. When you start the data you will be in the hole where the mantis boss is.

9. Kill it (which shouldn't be that hard) and you will get a power up for the sword.

10. Go to Watts and you can get the Mana Sword. Note: Do not try this more than once, it will mess up your data. Also you should make an extra data because you might mess up and the you wont be able to use the data anymore.

If you are thinking that the other 'mana sword gaining techniques' are dodgy, fear not. Go to the Mana fortress and kill as many enemies as it takes to get a chest. It will usually contain useless things, but eventually (after ages) you will get an orb. It may not be the final orb of the sword, if not it will be the orb for another weapon. Repeat until finally successful.

To get back into Potos after you get banished, you have to have all three people alive. Walk up to the guy at the gate, keep walking into him and keep pushing SELECT until you're on the other side.

This trick takes patience to do. Every time you get a Mana Seed, you will be able to increase your magic's level. But, you have to use the magic a lot to make it increase (which takes a while). Once you get your magic spells in level 7, they will start to be super-powered. They will not do it every time, but you will know when they do. Once the spells get into level 8, the spells will be super-powered other spells will be super-powered

Go to any chest in a dungeon that has an orb and open it, then use the magic rope to teleport to the entrance of the dungeon. Go to the nearest watt and have him forge the weapon. then return to the chest where you found the orb and another of the same type of orb will be there. repeat this process as many times as you'd like. (note: Do not forge your weapon past its highest phase or it will be turned back to it's very first stage i.e. if you forge your sword to its 9th and final stage the forge it once more it will become the rusty blade.)
