Hello.
I'm getting a DOS/4GW 2001 error when trying to start "Star Wars: Dark Forces" in MS-DOS. It says 07h (device not available). It does not happen in Windows. No matter which drive I try to load the game on, it does this frequently, but sometimes the game runs in DOS. Stonekeep also uses DOS/4GW, but when I attempt to run it directly in DOS, it never fails to run as long as the sound settings match the sound card. Stonekeep's disc is in like-new condition, while Dark Forces has some mild scratches and was buffed in the past. What could the cause be?
