TerASIC changed the memory part on the DE1 somewhere along the line and 
CocoFPGA stopped working with the newer boards.

Gary has re-written much of the core and is hoping to release a new version 
that will work on all DE1 boards, with other improvements as well.

The DE1 is host to a relatively large number of retro micro FPGA projects, 
including the C64, Amiga, Apple II, TRS-80 etc etc so I have no doubt Gary 
will overcome the niggly issues with CocoFPGA.
