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...

Well, that explains why you had GPIO_0 as inout in the original code! Did you change SNES_DATA to inout? I'm guessing yes since you can't make an assignment to a port if it's an input.
