Hidden artwork:
Place the game disc in a PC compatible CD-ROM drive to find various art from the
game in the "BMP" directory in .BMP format. 

Unlimited tokens:
Download the mini-game "Stuff" to your VMU. Then, save your game. Sell everything
you have and go to the Monster House. Buy as many tokens as you can. Put the
tokens in your VMU. Reset the game and load your game file. You will have the
money, items, and tokens. Next, sell the tokens and save. Go back to the Monster
House and buy even more tokens. Repeat this trick as needed.

Cooks:
Successfully complete all of the dungeons and save the game. After completing the
last dungeon, get Lady, save the game, then close the book. Wait for the credits to
complete and a FMV sequence will begin. Save the game when prompted after the
sequence. Exit, then load that game. Enter your monster house, go to encapsulate
monster, and "Cooks" will appear. Take him out, and he will be one of your monsters. 

Duplicate monsters:
Go to the town area with the "Moon Lighter" or "Moon Lighter S" item. Save the game
at Sword's House and go to the VMU machine in the Monster House. Download the
"Moon Lighter" or "Moon Lighter S" mini-game to the VMU. Download the monster to
be duplicated to the VMU. After downloading, exit the Monster House, then turn off the
Dreamcast without saving again. Start the game again and select the destination
save file. Go to the Monster House and load the monster from the VMU into the game.
If done correctly, both save files will now have a copy of the same monster. 

Use mini-games more than once:
Download the game to the VMU. Turn off the Dreamcast without saving the game. If
done correctly, the mini-game will be on the VMU and still will be in the game without
having to re-purchase it. Note: To save money, do note save the game after buying the
mini-game item.
