Ok I gave it a try. I really like it. I've been able to extract everything so far except sound. I can export it and it has a file size but when I try to play the MIDI in Winamp it says it's 0:00 long and won't play. It does, however, play in Windows Media Player. I don't know what the difference is...
Also it would be a nice feature to export each file in their native SCI format as well. Not mandatory, but it would make it as nice as the same feature in the DOS SCI Decoder that was released ages ago. I used to love putting sound resources into other games! Lol.
