Trouble interfacing FLASH pins to GPIO (retro game related)

Hey all, Just got an Altera DE1 dev board using the Cyclone II, and I'm working on a simple test that is literally just connecting the FLASH chip to the GPIO_0 bus. I'm not performing any logic...

You have SNES_RST as an input to the FPGA and you're not doing anything with it. Should this be an output to the cart and set low (assuming it's active high)?

What does SNES_ADDR(15) do?

And what actually sets SNES_ADDR on your board/cart? Is there software somewhere else that does this?
