To earn easy money playing roulette, first save the game when your at the casino. Bet 1,000 tokens on one number, then bet on the four lines of that number and the corners. Next, bet on the column, row, color and even or odd. Finally, bet on the half of the board that number lies on. If your number hits you will win the maximum amount of tokens possible. If your number does not hit then load the saved game.
For easier Ex bonuses for the dance to get Ex, use a PlayStation2 controller. Since the PlayStation2 controller is not Sixaxis capable, it will automatically pick up the normal shaking you would need for those situations, giving you an advantage in any battle where you would use Ex.
There are four weapons that are obtained from the god orbs, one for each of your characters:
The first you have to get is Atsuma's. Get this when you visit the sage. Afterward, there are three more you must find scattered throughout the game. One sage is right outside the sages' area you just go down the stair case and look around the entire tower; there will be a golem there. When you kill him you will get its core and a god orb.
Another one is in the desert outside the Junk City in one of the ruins, but the doors to it are locked. On the middle right side of the area, between the 2 ruined buildings, is a sink hole. Go to it and you will fall through there is another golem there who will give you a god orb after you defeat it.
Then there is the area where the Yokahama bridge was blown up. Go down to the river like you did when you swam across the first time, only this time don't go across. Instead, go down to the part of the river where you see pieces of a statue blown off. There will be a sandy part on the shore where you can get out. Walk around that area until you find the last golem in a kinda corner and you can get the last god orb from it
God orbs make the Iris wepons, which are the second strongest in the game (the strongest are the crystal weapons, which are found in the holy beast area outside of junk city; you can also find omega golem, one of the strongest golems obtainable).
The following is a great method to get plenty of Casino Chips easily. It involves the initial accumulation of a lot of chips (around 2,000). This can best be done by doing Golem Battles in the Casino. After you have around 2,000 chips, go outside of the Casino and save your game. Then, re-enter and head to the roulette table. Put 100 chips on as many numbers as you can, covering enough to give you a 50% chance of winning more chips than you sacrificed. If you win, take your earnings, go back outside, save, then repeat if you want more money. If not, load your previous save and try again. You can make more than 100,000 chips with this method.
Save your game and head into the casino. Fight Golem battles as much as you can and acquire at least 500 chips. Once you acquire the chips, save your game, then re-enter the casino. Play Bingo and put all of your chips on it. Multipliers make Bingo the most lucrative game to play, and if you lose, simply shut your game off and reload your old save to try again. Doing this will net you more than enough chips to buy each and every item in the prize menu.
When you reach where the Queen Of Ice and Toya are, skip all the dialogue and cinematics. After the cinematics, hold UP and skip when talking to the mystery man. You must start the fight before the message "Fire magic core removed" and "Karin has left the party" appears.
