OS9 Bad copy (9.0.4)
I tried running the Mac OS 9.0.4 iso in SheepShaver. I got an error from Mac OS saying "The system software on the startup disk only functions on the original media, not if copied to another drive." Obviously this is a bad copy.

We use the highest possible level of compression in 7-Zip when archiving software to save bandwidth and space, both server and client side. It's possible other utilities might not handle large heavily compressed 7z files perfectly.
That's not to say there aren't any corrupted files on the server, we simply don't have the time or ability to test every single file.
"The system software on the startup disk only functions on the original media, not if copied to another drive." is just the common error I used to get in SheepShaver. WinWorldPC does not have a bad copy of the .iso, as I know that it works when you burn the .iso to a CD using Roxio Toast and boot from it on a real PowerPC-based Macintosh.
Does removing the .iso from the volumes list and typing the .iso file name in the "CD-ROM Drive" field work?
(I think I've found this similar thread to "How do I use ISO files in Basilisk II build 142?")
