The
Game Boy Sound Manipulator is a Game Boy program that allows the user
to easily experiment with the different sound settings for Game Boy's
four types of sounds.
This tool is targeted at Game Boy
programmers, so you will have to know about Game Boy registers and
programming for this to be useful for you.
The program allows you to change each element of each sound register to any of its allowable values and immediately hear the sound with the new settings. Once you've made a sound you like you simply copy the four or five
bytes shown in the display to the appropriate registers during your
Game Boy program. For example Sound 1 has to have its values loaded
into ($ff10) - ($ff14) and then the sound will automatically play.
