i had uploaded the soundbank.gm once but i guess it got deleted as there weren't any downloads for some time - but Oracle has a page with sounbanks back up again:
http://www.oracle.com/technetwork/java/ ... 35798.htmldownload and extract - create a folder called audio in Java/jreX/lib/ - copy the extracted soundbank-X.gm into created audio folder and rename it to soundbank.gm
haven-res.jar ( extract with i.e. 7zip) sfx/music folder contains res files with midi in it so you can't just play it with a midi player - you'd need to use a tool like boshaws Resource Layer Utility
