Keep in mind some DRM models like the older SecuROM supposedly liked to complain if they detected virtual drives (that's how pirating is done), but I've never had a game complain about mine.
Kinda funny you mentioned that. The reason i have Alcohol is because some versions of SecuROM do not like my physical DVD-ROM so I had to copy the image over and launch them through the virtual drive. [e digicons]:grin:[/e]
