@Zach do you have an oscilloscope on hand? At least a multi-meter? If you run the main as an empty function, do the 3 LED banks still light up, even though dimly? If you can, check the voltage from the pin to the ground. Take notes. Then, put the main loop back in and measure the voltage on the pins with LED banks that aren't lightning up. What do you see? Of course, you could try just try other pins and if they work alright, just make compilation defines for each board and that'll make it easier to recompile your program as needed.
