The main work that I have done so far that is durable is extracting the graphics from the resource forks of the game files. This turned out to be more work that I expected. I wasn't able to find a simple way to save the images in a modern format. My solution was to use a outdated trial/beta version of Resorcerer that had been carbonized, so it runs on Mac OS X to load the images. Since it wouldn't allow me to export the images, I took screen shots of strips of the images. Then I wrote a ruby script to automatically load up the strips and extract the images based on a map of the sizes I fed it.
I now have the graphics extracted into png format so I can move on with development for the most part and save getting the sounds for later. I have a copy of AudioHijackPro, which I am planning on using to record each sound as I play it in Resorcerer and then cut in up in a audio editing program.
