On 1998-08-12, Oliver Richman announced a DOS port of rogue on rgrr, and said to go to <http://www.pathcom.com/~simex/opr/index.html> for sources. Now, there wasn't actually any sources, just a zipfile, <http://www.pathcom.com/~simex/opr/dosrogue.zip>, with an .exe and a README. Then on 1998-08-18 he put up a new version with a TERMCAP file, and that is why the README says "RELEASE 2".
