Sound Test

The Sound Test is a hidden feature in Hello Kitty World. It was documented by cah4e3. On the おしまい (the end) screen, quickly and correctly pressing A + B + Start + Select will enable it.
The Sound Test is non-visual and only responds to button presses to play music. This includes unused melodies, normally exclusive to Balloon Kid and Balloon Fight GB.
