Hi Brian and congratulations on your awesome work!!!!
This is not really an issue, but just as we are developing cores for Deca board we just need a way to implement your DDR3 controller to allow a video frame buffer for most of the cores at https://github.com/DECAfpga to output a proper HDMI video with standard resolution to make it compatible with the majority of monitors.
If you have the expertise to do that, we would love to see that example of use!!!
The Arcade cores would be a perfect target as they do not require anything else but the Deca and a Keyboard.
