DE0 Board for 1chipMSX

I bought a DE0 board to implement the 1chipMSX core but have just realised there is no onboard sound. Is there any way I can get stereo sound out or will I need to get hold of a DE1 board to do this? I'm totally new to FPGA programming so I'm making my first tentative steps. I've seen videos of a DE0 running Pacman and that had sound so I'm a little confused!

You can use the expansion connectors to add some Audio codec to the board. 

Using I2S or the like, it's a 4 wire interface, depending on the type of chip you use. 

 

For the I2S interface, you might start with the one from Opencores, or from the MP3-Player example in the Altera-Wiki (which seems to stem from opencores, too).

Thanks! It looks like the MSX core actually only outputs PWM which has been converted to some kind of analogue output on the expansion bus. Not sure how good the quality will be though - but we'll see.

At first I wanted to propose a PWM output too, but didn't have the heart, as you explicitly asked for Stereo. :D
