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...

Very interesting project do you have here...

I suppose the 3.3V are for powering out a DS card. In this case, as you have an already powered board, you can leave it unconnected. The GND pins should be connected, however, or you will have floating grounds. Check also the voltage levels of any I/O going from/to the FPGA when making pin assignments in Quartus.
