Emulate Nintendo DS card via DE1 GPIO pins

Hi guys, I'm trying to emulate a very simple Nintendo DS card through the GPIO pins on a DE1 board. I'm familiar with the Nintendo DS card protocol, though I'm still a newbie regarding digital logic...

Good news!

I finally managed to get some good output from the DS card pins.

It looks like it was working all along. In my first attempts, my SignalTap trigger was capturing signal data at the wrong time, because of noise when the Nintendo DS boots.

I use a better trigger now, and signals are getting through nicely.

Now it's just a matter of time before I can emulate a real Nintendo DS card :).
