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...

Yeah, this is going to be a really fun project :).

I let the power signal coming from the DS float, and connected the ds card gnd signal to the DE1's GPIO_1 GND.

In the assignment editor in Quartus, the I/O standard for all pins is set to 3.3-V LVTTL, I think this is correct.

Though, still no dice :(.
