First of all we will need some things:
-A GameBoy to show track information and control the playing.
-A GameBoy cartridge: we will need it to interface the GameBoy to a board.
-An ATAPI drive to play the CD.
-A 12v-5v power supply.
-An interface board: we can find it at http://personales.ya.com/proyecto_gb
. Go to Hardware section and build the schematics. We will talk about later.
