A quick look and only thing I can see that would make it not work on v1.0+ is the LedControl library and AFAIK it has since been updated to be 1.0+ compatible. Attached is a demo code I did for 2x MAX7219 chips arranged as a 16x8 matrix. I have since updated it to kern the fonts but don't have the code here with me at work.
