You do not write exactly how you tried to mount the image in SheepShaver.
Any format should work, as long as it is in a read/write format. The image file should then be locked in the Sierra Finder to convince the software that it is on a (read-only) CD.
Best try an image created in Disk Utility in DVD/CD Master (.cdr) format.
Add the image file to the volumes list in SheepShaver preferences, then quit and start again SheepShaver. Make sure the image is NOT mounted in Sierra.
Macintosh Garden has an .iso disk image of this game for download. It can be mounted fine in both SheepShaver and BasiliskII on my Sierra machine. As the game is 68k, you may also want to try it in BasiliskII.
Thank you so much for taking the time to respond!
I checked out Macintosh Garden and unfortunately that's a different version of the game (Sapphire Falls). I do have an ISO of Jump Start Haunted Island and I locked it in Sierra as you suggest. I copied it to SheepShaver and used Virtual CD manager to "Create CD/DVD Toast image", but I still can't open it as an actual CD. Then I tried adding the ISO to the volumes list in SheepShaver but that seems to have failed too. I keep getting the message "Background script error: Finder got an error: Can't get alias "Unix:SendToMacOS9". Then it just goes into total meltdown and keeps flashing the message until I force quit SheepShaver. Should I copy the ISO to the Mac OS 9 desktop first?
I know I'm missing something major and apologize for my stupidity. I just don't know how to do it correctly. Thanks in advance!
