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.

the audile software is a free rom image. You need to buy a flash card to put the rom image in.

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:

That's awesome, but same here, I would like to know more about how you did it, I could probably do this for my friend, it looks neat. :-)

That was cool. Obviously it's not going to be on my top 20 music list anytime soon, but the concept is certainly there. Nice one
