This game works well in SheepShaver with some slowdowns. But, that's not annoying. However, it crashes with BII after the start. I don't know why.

Can someone check this on SheepShaver and Basilisk II? I don't have the proper knowledge on emulators! Let me know the results! Thanks!

I've tested this game (physical CD, non-copy) on my Indigo iMac G3 (2000, 350MHz) running Mac OS 9.2.1 and had the same positive results as the other tester did.

Quite right, mrdav. I had not tested mounting the image using Toast, only the Virtual CD/DVD Utility and that is mounting only the Win partition in OS 9, whereas Toast is mounting both OK.

That's a 1st for me (where the Virtual CD utility fails to mount the Mac partition) so I will need to monitor for that possibility in the future.

Perhaps of note, the toast and .iso are returning different checksums tho' both appear to be OK, but not quite identical.

The toast image was removed from the DL's - the hybrid .iso being the more compatible for all platforms, + Toast can mount .iso's as easily as any CD image. - I also installed from the .iso and tested the game as working fine (Mac OS 9.1, beige G3).

Both copies here are hybrid images. (i.e. both have proper Mac and Win partitions). It is just that the Mac partition may not mount in OS X. For example, it will not mount for me in Snow Leopard. However, it mounts just fine on my old iMac running Mac OS 9.2.2. This sometimes happens with disc images of older CDs. The images from the two archives seem to be identical, and both are good. However, we only need to keep one.

Uploaded another copy that I made using ImgBurn on Windows 10. Is this OK? Is there any difference between the two files? Does it have a true Mac partition?

Thanks MikeTomTom! I should try that sometime. I have never used ImgBurn to make ISO files, but I will use that program on my Windows 10 computers just to make an image out of this CD even if my PowerBook G4 running OS X Tiger doesn't cope with some hybrid CDs. I am still trying to get a true Mac partition out of this entry's attempted TOAST image.

a problem with the TOAST image that I created. It appears to be unreadable.

Not unreadable, but it is missing the Mac part of the hybrid CD. Only the Windows part has been archived, which appears to be intact (mounts OK using the Virtual CD/DVD Utility from here).

I haven't tried running it in Windows. The content consists of files for a Windows 3.1/95-98 (contains Win16 & Win32 coding).

You perhaps would have had better results if you were able to archive the CD on a Windows platform using ImgBurn (best for perfect hybrids), instead of Toast under OS X.

There was a problem with the TOAST image that I created. It appears to be unreadable. Someone should upload a better copy of this game if he/she has a physical copy of the CD! I will be eternally grateful! Mine had problems though. Otherwise, it is well worth documenting this rare CD-ROM to the Macintosh Garden for preservation!
