Design Files

hello,

I try to use NIOSIDE and Quartus so I download the example files given by altera. But there are only files for cyclone 2c35 but mine is 2c20 so I can not use the programmer (on quartus) and then run the example given. Does someone has the files I am looking for? or should I change something in the files I use to be useable with a cyclone 2c20?

thanks very much,

Eléa
