Easy money:
Go to the question mark west of Fou-Lou's Temple. Go to the area where there was a burning forest. When you fight a Gold Gang and kill it with physical attacks you will get slightly over 1,000 Zenny. If you want even more money, kill it with magical attacks for over 10,000 Zenny. Repeat this as needed.

In-game reset:
Press Start + Select + L1 + R1 + L2 + R2 during game play.

Skip intermission sequence:
Press Start to pause game play, then press X to skip the current intermission sequence.

Alternate ending:
At the end of the game, answer all of Fou-Lu's questions "Maybe so...". You will be merged with Fou-Lu and will play as the Infinity Dragon (Fou-Lu and Ryu God form). Then, just wipe out your ex-partners to get the ending.

Healing with apples:
When you go into the woods to find the mayor, you have to use "apples" to lure out an animal. If you run out, find the tree that the man told you about where you can find more. Use Ershil's personal action and head butt the tree. An apple will drop down. The apple is a great healing item for early in the game, healing 100 HP. This may not seem like much, but if many apples, they work well. Stock up to get a full 99.

Finding Rider:
Use the following steps to find Rider, the game's toughest monster. Go to Mutko. After passing through the Tomb, enter Mutko from the south side. Then, enter the cave in the upper left corner. Have Eshrin headbutt the crack in the wall. Enter the opening. Go through the next three rooms. You should find a treasure chest and then a dead end. You can find Dragon Tear in the chest, as well as Rider. He has about 400,000 HP. To make things worse, he regenerates half of it each round. He can also cast some dangerous attacks, such as Disaster and Primus. Use Pilfer to steal a very valuable item from him -- King's Armor, which has Def 100.

Defeating Maman:
In the woods where you find the mayor is a tree full of apples. Hit it with Ershin and stock up on apples. Head through the forest to where you find the mayor. You have to fight Maman at this location. Use an apple to distract it for a turn. If you have enough, the Maman will not attack during the entire battle.

Defeating Fou-Lu:
When you fight Fou-Lu alone as Ryu at the end of the game, just transform into Kaiser and leave it to him. If he dies, transform into another dragon or attack him by healing yourself. Fou-Lu will not transform into Tyrant or Astral or any other dragon-forms that he has.
