I can confirm that a clonecd image of bf1942 with CloneCD 4.0.1.6 works perfectly in Daemon Tools 3.23. As Copy Trooper said, bf1942 began life as 2.60x so there was no pre gap data to check. Now I also know why some people were having problems with Clonecd and SD 2.80x. You can also bet your ass that one of the next versions of SD2 will incorporate the media description trickery that Securom New 4.8X uses.
