Really? Wow! Maybe you could try contacting Christian Schaub http://www.webstube.com/pages/software/patterneditor/index.htm http://www.webstube.com/pages/software/patterneditor/index.h... who has created a RB pattern editor for Mac. I guess he may know a bit about the format :) There was also a guy called Matthias Schill who made the pattern editor for Windows but unfortunately his webpage is down. Good luck!
