i don't think there is much secret.
> download the original game, then the append one

copy the daijyobi_addscene files
paste it on the original folder, go to where is same ''addscene'' and substitute it.
test if girls is voice-ed on gallery event.
Tried again today and nothing, I don't get the voice in the scenes and after clicking on the append icon after finishing the game, it does nothing, although I can hear the voices at the voice test in the setup menu, and at the right bottom corner it says that it is the the right version with the append..
The process I'm doing is:
1 - Extracting both the Main game and the Append rar.
2 - Using the cmd to extract the Windows folder. (I don't do anything with the "MaouHarem_Append" folder that comes after extracting the append rar.)
3 - Copying and paste the new Windows folder files created by the cmd (the Event and the Voice folders, the 4 files on the Windows folder and the System txt file on the StreamingAssets folder), into the Main Game folders, the right ones of course, substituting the ones of the original game when asked to.
4 - After doing all this, I try to run the game.
