I think I found all files of Kaduria. There were of course more than just tiles, like fonts and misc. graphics. I remember that there was external data only for the precalculated light maps. The latest source files were recovered from a single source, that was exciting. The previous sources were stored month earlier. I don't know what I was doing, but now I'm going to make backups to everywhere I can. I think the latest source was really the latest and I don't have to do anything again, like I have to do with Stile where I was able to recover only the release version (0.82) sources while I had continued it later.
Now I have to wait what happens with VC++ registering which failed, because M$ registering message doesn't get through. They should fucking mail it as a real paper letter. I just need the registering code. Meanwhile I installed Code::Blocks but it's a temporary solution. It's a beta/alpha project and even years older DevC++ seems to be more stable. One of the great mysteries is why they didn't continue the development of DevC++? Just couple of tweaks (better search options like 'find by reference' and internal book keeping of source files) and it would be a great IDE. What the hell have the developers been doing all these years?
