NOTE: This test version contains another test codes related to score.ini files, and the feature has not tested yet in my side. So please backup your score.ini files in advance to use this test version. After finished testing, please restore score.ini files.
Fixed in the rev173.
When changing the AutoVolume in the Configuration (System->AUTOVOLUME), the volume of the song audio previews is affected, too. I would think this is not intended?
