Oh, and there are cyclical references going on, I don't think the weak metaphor I'm using here can hold that part up very well:)</div><div><br></div><div>I can't say anything of real use WRT extracting stuff from a completely hosed image; I've needed at least a recovery console to open in order to make it back to a state that I can recover objects from. Basically the image format is currently beyond my experience, but if I wanted to find out how it works, the first thing I would try is pulling down VMMaker and looking at the Slang code for the object memory itself. This could be terrible advice though, so I'd go for a second opinion if I was you:)</div><div><br></div><div>If just you want to move some objects between two images, you might want to check out SmartRefStream. </div><div><br></div><div>I've also longed to see some tools for image exploration/visualization. I'm really excited about the work of Craig Latta in this area. I would strongly recommend that you check out Spoon when you can. </div></body></html>
