Your post is lacking way too much information.
Firstly, who says that it's free now?
Next, how did you mount your directories?
Which file did you run to start the game?
What comes after the "Program:" text at the top of the DOSBox window?

I'm asking these things because the game plays perfectly for me, with default DOSBox settings.

who says that it's free now?

Well, I say it´s free because I downloaded it from the new Home of the Underdogs, and supposedly they only let you download freeware games now.

how did you mount your directories?

Mount l c:\
l:
cd games
cd vision

Which file did you run to start the game?

Either boom.exe or btl.exe
Using btl.exe leads me directly to the blue screen, while boom.exe leads me to the title screen, then the blue screen.

I tried the other exes in the directory,but they don´t do anything.

What comes after the "Program:" text at the top of the DOSBox window?

BTL

What exactly gave you that idea?

(Please don't lock this thread just yet; I'd like to know.)

EDIT: The solution is trivial. If the game is installed to C:\GAMES\VISION and you mount C:\GAMES\VISION as drive C in DOSBox, you'll get the blue screens. Mount C:\GAMES as drive C instead.

He can contact an admin if he's sure this game is legally free to download,
so this thread will be unlocked again.
