you need a flashcard for the GBA SP. A Flashcard is an programmable cartridge where you can put one or more rom images. You can find all the informations here:

Before you got a flash card you can play with the rom using an emulator.

Hi, thanks. I started with the Christofer Optical Theremin here:

RS Optical Theremin

and then I've tried various photoresistors/photodiode. I've tried both ultrabright leds and IR ones to beam the optical sensors.

Finally I've added this filter to make the sound smoother and a simple transistor based amp to make it louder:
