GAMES:The 7th Guest
The 7th Guest is now available on ScummVM, so it is recommended that you use that instead of DOSBox.
The game will install and run with these CD-ROM options:
mount d drive:\ -t cdrom
You may need to change some options to make the music during the title sequence and credits work. The 7th Guest is extremely CD-ROM intensive, and will have noticeable loading times no matter what you do if you run it directly from disc. It will run much faster if you make an image of the disc or copy its contents to a directory on your hard drive. For example:
mount d: c:\whatever\t7gdisc1.iso -t iso
mount d: c:\whatever\t7gdisc2directory
