Please let me ask you another question.
I'm not very good at English, so it's possible my understanding is wrong.
I'm not very good at English, so my understanding may be wrong, but I'd like to ask about "Aidio→Custom Sound Effect→filename(no extension)" in the dialogue script.
Does "filename(no extension)" mean that the feature is not yet installed?
If this feature is available, where do I put the Custom Sound File?
Also, about "Meta→Set CG", is it possible to use this script to display a background that I prepared by myself?
