I've got this old book which tells about the glory days (i.e. the eighties) of the Chaos Computer Club of Hamburg. A member of this Club cracked NASA's computers sometime in the eighties, apparently a big media thing back then.
Anyhow, there's also a chapter about neonazi software in that book. Unfortunately I can't give you titles; the book is still at my parents' place. I drew the conclusion if there were neonazi games in the eighties there also must be the same crap nowadays.
I can't be bothered to do a search on internet, but I'm sure some googling will yield some results.
