The github code works after a slight rewrite of the decrypt loop ending condition (e.g. cast the file header buffer directly to char* instead of going via int).

That discovery you made about the unpacked music in the dos-version should suffice to circumvent the need of using it for the only strictly legal purpose though, so that’s good to know! Personally, however, I wanted to use the unpacker for something a bit more shady (getting the Drek animation the lazy way), but I can’t imagine the devs would have any problems with it given that it’s being used for private purposes only… O.o

It seems these packfiles are encrypted. I was able to find winv2 source and build an unpacker. I put it here:

And hopefully someone else can commit some small packfile cases and help me improve this. But anyway, I didn’t end up using it, because…

Finally and most importantly:

• enya.xm is “exile” from 1988’s Watermark.
• aquarium.s3m is a strange demo or demake version of awesome’s “aquarium” (search for AWS_AQUA.XM)
