These Norns are the culmination of a community project to improve the C3/DS 
Genomes and to fix many of their problems, such as incomplete biochemistry, 
broken drives, instincts, and chemical reactions, as well as unused neurons 
and stimuli. The goal was to put back everything from previous games that was 
missing in C3/DS and more, to allow them to live up to the full potential of 
the C3 game engine and their more sophisticated brains and biochemistry. 
They have 80+ changes, including over 60 new genes and a new organ and brain 
lobe that help regulate their hunger.

The changes are detailed in the CFF project thread at:

Genetics Note:  These creatures are genetically compatible with any creatures 
based on the CFE genome, and problems mixing with most standard non-CFE 
types should be rare.
