When I add it to the volumes list in SS settings, it says that it's an unknown drive and that it needs to be initialized. What should I do?

I didn't know that the CD version existed. Thank you, fantastic upload!

Try G3 Throttle to calm it down! Wink

Whoever uploaded it to Mediafire: THANK YOU!

I installed it on an iMac G3 running OS 9.2...RUNS LIKE A DREAM. Animation! Sound! Black and white graphics! Memories intact! YESSS!

One problem: animations were a bit fast.

A great find, but I was dismayed when I saw it had been uploaded as a .img. This may need to be re-uploaded as a Stuffit of the .img. Most .img's have resource forks, these will now be lost on the file uploaded.
