I've been examining Jonny Quest: Cover-Up At Roswell (came out 1996), and I'm trying to get at its backgrounds, sound effects, and so on.

As far as I can tell, each scenario's assets are packed in extensionless files with a RIFX header. These files contain an internal directory naming all the assets inside, including some AIFFs and .pics, and also has references to other folders on the disc for quicktime animations.

I'm just kind of stumped on how to actually get at these. I threw it into Game Audio Plugin and a couple familiar game archive extractors, but nothing. I'm not finding much on RIFX for being used as an archive or directory. It's probably something really simple, but I'm inexperienced with this.

It might only take a few seconds for someone with experience to figure out what I have to do with it, so it'd be much appreciated if someone could take a look at an example file at http://chronofan.com/Zeality/HCAST (no extension). Thanks.

Edit: Riffviewer can open the hierarchy. I'm guessing that the assets are stored in those BITD offsets. There's a CLUT chunk right before them.
