Tales of Symphonia

In the top-left corner of Flanoir, there are three statues. Look closely, and you can see that one of them is of Namco's oldest mascot, Pac-Man!

When playing Red Light, Green Light in Tethe'alla, press Start when the Sea-Katz begin to turn around. You'll be asked if you want to quit. Select no, and when you go back to the game, Genis will be standing still regardless of whether or not he was in the middle of a move. This is a cheap, easy way to ensure that you never get caught by the Sea-Katz when he turns around.

After Corrine has already died and you have defeated the Dark Dragon and walked through the doors in Mitho's Castle, go all the way back to Iselia. Once there you should see a skit involving Sheena hearing Corrine talking to her. After that go to the Temple Of Martel. Once there go to the place where you first met the angel. When you enter the area you should see a secret scene with Corrine in his true form.

Tech glitch allows you to have T-type and S-type techs at the same time.
This is how it works: (for example)

1. Put Lloyd to the first place of your party and set Genis' Eruption to Lloyd's C-stick shortcut.
2. Switch Lloyd out of your party.
3. Have Genis forgot his Eruption and switch him to S-type. Then battle until he learns Flame Lance.
4. Switch Genis back to T-type.
5. Save the game! (Do not save or look at the tech list after this)
6. Now put Lloyd back to the first place of your party.
7. Go to battle and use that Eruption shortcut with Lloyd. Genis must relearn Explosion during this battle, if not, Eruption shortcut from C-stick is gone.
8. And if you didn't succeed, repeat from the step 5. If you succeed you have now both Genis' Explosion and Flame Lance.

After you've obtained the sacred stone key item in Mithos's castle, go to Sybak, and examine the weird red book with an exsphere in one of the bookshelves at the library, then go to Heimdall and talk to the man near the windmill, after that, go back to Sybak and check the red book again, you will then enter the cursed book of niflheim, the most difficult dungeon in the game.
