>The reason for my DiscJuggler suggestion is because SafeDisc 2.51+ has more protection in the pre-groove which DJ handles better than CCD or Alc and writes more properly.
Actually it only becomes relevant with sd 2.8. However, BF 1942, though mastered with sd 2.6, contains the pre-gap info that the guard module for sd 2.8+ checks so if the game is updated to the latest version, a copy that previously was good may then fail.
If your reader is sufficiently accurate and you have a 2 sheep writer then a discjuggler copy is the best you can get because it is the only app that actually reads and writes the pre-gap info (alcohol & blindwrite by-pass that aspect of the guard module by a different method).
However, dj requires a very accurate reader for a sd 2.8+ copy to work. Plextor cdrws, Toshiba dvds and Asus cdrws will all be ok. However, Lite-on drives are hit or miss and you'll need some luck to get a dj copy of a sd 2.8+ protected game to work if you use a Litey as the reader (mine all fail but reading with my Asus CRW-5224A succeeds).
If your dj copy fails (and remember that you'll need an atip hiding utility if playing the copy from a writer though not from an ordinary cd/dvd rom), then the easiest solution for you would be to use alcohol with safedisc (not safedisc 2/3) datatype settings. Just remember to enable Ignore media type in alcohol's emulation options if you want to run the back-up from one of your writers.
