  • Bad news: I don't plan to spend much more time developing drago.
  • Good news: I am opensourcing it [ext] https://github.com/GillesArcas/Drago.
    Unfortunately, I am afraid nobody will invest time to continue to develop it but at least it will be feasible.

Problems / Solutions

Is there a way to continue a game with fuego ? It works with Gnugo but if I open a started game to continue it with Fuego, the program will just be stuck (the mouse cursor indicating it's thinking...). Gogui claims this works fine, but Gogui doesn't seem to work on Win 7, 64 bits. Also how to change parameters of Fuego when using Drago ? The basic parameters are a bit week, and Fuego doesn't just have a "level". It is 4 parameters that modify the accuracy... Besides those 2 issues Drago is very nice...

willemien I think it is a problem in cygwin (the translater from C++ sourcecode to windows executable) I don't know who and how it can be solved sorry
