--- Comment #6 from drakh drakh@spamcop.net 2008-07-24 14:57:07 --- Nicolas, I think you're running "FIREFGHT.EXE" directly, without having first having set up the game with "LOADER.EXE". As far as I can tell, the bug is still there in the latest GIT.
As for running it on Windows, Fire Fight did not support Win2k until version 1.2, but I've been unable to locate a working copy of the shareware edition for download. In 1.0, it seems that the loader simply refuses to run unless Windows version is set to 9x.
