GameBoy CD Player

Build a CD player with an old GameBoy, an ATAPI drive and some electronics. The CD player it's a kind of game cartridge to play CD. This is the final version, plug it to a GameBoy and listen to music!

Wanna see how it works?

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.

We need to wire the GameBoy pins to a board. We can open it, but we prefer to preserve the GameBoy to play our favourite games. So let's make an adaptor cartridge. Get a boring game and open it with a screwdriver, be careful not to broke the board inside.Well Prince of Persia was not boring but I had no one else.

We see some chips, the game program and some interface chips. We need to remove it, so let's use a cutter to cut it. We could use a soldering iron but that would wear away the board.

Get a ribbon cable and solder it to the board following a logical order, I mean, the pin 1 of the cartridge to the pin 1 of the ribbon cable. I used an IDE cable as a ribbon cable.Follow the pins paths to get a termination solder point,it's easier and better(then you can close the cartrigde).Check for shortcircuits when you finish. If it's all ok, fix the cable to the board with glue.

In order to put the cartridge inside we need to cut the plastic box. Use a cutter or a tool you consider better.

I will not cover the board construction process, but i will put the schematics and some comments. I've made modular schematics, you must interconnect them to have the complete board.Axx , Dxx and /RD,/WR,RESET signals come from the GameBoy cartridge.GND and +5V are common to the power supply,chips and GameBoy.You must burn the z80cdplayer.gb in the EPROM. Sorry it's in spanish I will translate it some day.

The schematics also are at http://personales.ya.com/proyecto_gb/

This is the last step. We must put it all in a box to make it useful. You can use a wood box,plastic box or even a cardboard box!! With imagination all it's possible.You can see how it works at videos section of http://personales.ya.com/proyecto_gb/
