Yeah, the loss of cdenable.sys is annoying. I wish someone would try to build a 64-bit version. The driver signing wouldn't an issue for me as I override it for other drivers. But iso images work, so at least there's a way around it. BTW, you can image the CDs in Windows just fine.
As for HFVExplorer, I haven't noticed any problems with trashed resource forks, but then I mostly do any moving between images inside SheepShaver. I did use HFVExplorer to copy files from images to floppies on occasion and didn't notice any trouble there. But I'll pay closer attention next time.
