Boktai: The Sun Is in Your Hand Cheats

1. Get a tonniar rm. You can get one from the Count by burning him with a skylight.
2. Observe what time the sun rises in your game (by going into an Immortal dungeon at night), then save in the area with the solar tree
3. Set the time in the main menu ''Options'' screen to one minute before your sunrise (such as 5:59)
4. Hurry and get under the solar tree. At the crack of dawn, dew will fall and convert your tonniar into a Mr. RainNot.
5. Walk east one screen and use Mr. RainNot.

You now have two bars of sunlight at all times until the next sundown. Now, to keep your sunlight permanently, each time you play boktai set the clock to daytime of the day you used the Rainnot. With this method you will have sunlight, day or night, every time you play boktai!
