This is a really simple mod that overrides one file, disabling the intro splash video.
The file is a short/blank bk2 video file. The common method of renaming a text file to override the video doesn't work in this case, as it causes a crash.
Honestly, this can barely be called a mod, but I figured someone out there might appreciate the time saved (especially if you're opening/closing DOS2 a lot to test things out).
