Hi, since Quarry doesn't seem to be developed anymore, and isn't that user friendly when going through sgfs, I tried Drago and really liked it. However, there's the need to use wine, which I try to avoid for a couple of reasons.
I don't want to annoy you with this, but did you try http://www.lazarus.freepascal.org/
? Seems you can compile your Delphi program for different platforms there. I'm not sure how good the result would be, but I guess it couldn't harm to give it a try and find someone to test the result afterwards...
Anyway, thanks for your effort! --Til
