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...

Fixed it.

Didn't have the Data pins set to 'Z' when not being accessed.

SNES_DATA <= FL_DQ when (SNES_ROMSEL = '0') else "ZZZZZZZZ";

That works properly.
