Boktai The Sun Is in Your Hand Cheats

If the Sun isn't on your side, you can easily get more than 7 bars
on your Solar Sensor. Simply get a black light (they look purple,
and make things seem to glow). These give off lot's of UV rays,
which the Solar Sensor then detects! You need to hold it pretty
close to get a good reading, and it's easy with one of the long,
cylinder lights, which are pretty cheap and fun to play with.
