I found an extremely helpful tool in this task - it's called Rezycle. I've tried it and can recommend it - it does exactly what it says it's supposed to do, and does a darn good job with MOST things I've thrown at it. What it does is reads in the resources inside the file's resource fork, extracts them, and converts what it can to more modern formats. As you can imagine, this helps immensely in preparing for reviving an old Mac OS 9-only game. That said, anyone else found any useful tools for this sort of thing (that run in Snow Leopard)?
