I know it's been a while since I updated this project. I'm better at working on the projects than documenting them. I've been focused on some other projects for a while, but now I've got some time and renewed interest, so expect updates soon.

I just finished spinning a new IO board for this project. It's a simple one that incorporates an RTC chip, a codec with line in/out and headphone out, PS/2 keyboard, and an aux output for the LED matrix. I've been working on an i2c master instance for my SoC, which I can then use to program the codec. Untimately, I want to use the codec to serve as an output for the PCM/WAV audio for the game. So next update will talk about the audio interface and progress on integrating the audio into Doom.
