|Programs supporting this format|
The encrypted LBA texts from the LBA 1 Preview Version. Note: The .DIA extension is officially also the normal LBA Texts (Dialogs file) extension, but we already use .LBT for that.
The format is the same, as that for the normal texts, but each text entry is encrypted. The encryption scheme used, is still unknown, but it might well be just simple XOR encryption.
