I'm currently playing Boktai. I really like it, and I enjoy the custom sun-adjusting controls in the My Boy! emulator on Android. As far as I know, it's the only emulator that has sun sensor support. The sun sensor was only for the Boktai games, and was an integral part of the gameplay. I want to recapture the feeling of actually using the sun sensor. My Boy! clearly has an option to use your phone's camera or whatever, but it doesn't seem to work. Any help? I'm using an LG K20. Maybe my phone doesn't support it, or maybe I'm just doing something stupid, but any help will be appreciated.
