Quote from the DGenMOD 2.1.0.0 User Manual:
The modified dynamic campaign generator (DGenMOD) is a further development of the generator, developed by Vadim "Starshoy" Kolosov for 1C:Maddox Games. The new generator is based on the original code and algorithms of DGen version 4.0.4.1. DGenMOD is fully compatible with Il-2 Sturmovik version 4.11 m or above. The generator can be used both with the original version of the game and the MOD version (the mod does not matter).
WARNING! As of DGenMOD version 2.0.5.0, the files containing aicrafts definitions, available loadouts and maps related files are only fully compatible with: DGenPack (version 3.0) itself based on the Team Daidalos patch (4.14). The maintenance of separate configuration files (for HSFX, DBW, etc...) has been discontinued. Files for these modpacks are no longer provided with the generator."
But, you can edit the default DGenMOD dat-files so they work with other mods in Il-2 Sturmovik version 4.11 m or above.
