It seems that the config file for 3c120 actually works. It also outputs from my jtag that is says 3c120 so it seems compatible

My Altera DE2-115 outputs the following 

$ jtagconfig1) USB-Blaster 
  020F70DD   EP3C120/EP4CE115

Oh, it looks like the EP4CE115 (used in the DE-115) shares the same IDCODE as the EP3C120 - which is why the Quartus programmer detects them as such. I guess their package pinouts will be different though. But it is good to know that the Nios config file works :)
