Sega CD PCM sound is working.

I finally got PCM sound working on the Sega CD. It's not very difficult to get Sega CD sound working. The hardest part is figuring out all the little things that were needed. I spent the better part of two days figuring it out. I'm getting really comfortable with the Main/Sub CPU communications. This was always something that worried me when I was looking at Sega CD development.

I also fixed a bug that was causing a problem playing CD audio tracks.

On another note, I've done some work in figuring out how to boot up a NEC PC-FX CD. The limited version of Magic Engine FX (http://www.magicengine.com/) makes it difficult, but I've managed to get around most of it. Now, I have to disassemble the program and figure out how to get it working. Like the 3DO version, this will be done in between versions for now. It's a nice little break from the PCM stuff.

The next thing on the list is game AI.
