Well those tut's are wrong. You only need one virtual drive as you will only be needing one CD image at a time mounted...since you can only play one game at a time. While I don't have a bunch of games setup for it...I do have a few, and I use that GameEx ini and the launcher...no batch scripts, or any thing else...and I'm able to play what ever game with just once virtual drive, since the launcher will mount and dismount CD images. Tho I just edited my Sega package by adding a line to the DreamCast INI to make sure Daemon Tools dismounts the CD image.
