I've turned them off and the problem still occurs. Hidden, system and read only flags are preserved from the original source. The date time flags are altered or not depending on those settings. You can test it yourself, take a romset with a few roms in it and make one read only, one system, one hidden. Now rebuild that rom, the target rom has the same attributes.

Thanks,
