Hi again. I'm still trying to make it work.
I read in the installation intructions that if i get a gray screen (exactly like in my case) i must set variable gl_mode "0" in the config.cfg file. In the Q2 CD that i got there was not such file in the BaseQ2 directory, here are its contents:
gamex86.dll 357376
pak0.pak 18399773
players Dir
video Dir
So, i just used a text editor to create the file and enter gl_mode "0" as its first line.
I tried to run the game again but nothing.. the same gray screen with no sound or anything.
I could appreciate some help here, from what i read there is at least one person with similar setup, who was able to start the game.
