I have tested adding it to SGB and the only problem that I can found is the texture naming for the heroines. SGB said that they can't found the texture file, and I think it's because of the naming problem for the texture. For example, when I tried to import Edit_Heroine03_A, the warning said that the name of the texture "Akia_0.png" can't be found. So I have to rename the texture file first. The other stuffs can be added fine.
By the way, I like the edit you did. It's really a problem for me, when creating a character from SGB's 3D Character Editor, you can only get the 3D character, you didn't get the image for the dialogue. So, I can't show the expressiveness in the dialogues because the face didn't match. With the edit, both the 3D and the face image can be get, so it will really help to solve that problem.
Great job with the submission. XD
