Yep, another thing with GARbro is that it takes a while to identify the file types of the subfolders. This don't seem to happend extracting other games, apparently is just something that happens with MilkFactory games. Once GARbro identifies that there are sound files you can automatically extract them with the correct extension. Altought, the alternative I used is to add the .ogg extension to all the files inside the voice folders after extacting them. You can do that manually or apply this command in cmd if your'e using windows: ren *.(current extension name) *.(new extension name). So, to chance all file extensions to .ogg (sound) I used: ren *. *.ogg . I also used this method for the video files, images and sound effects in the other folders, again, is kind of complicated since they have garbled file names so if someone know to fix them it would be appreciated.
