Thanks for the information, SirDave.
When Dreamcatcher reissued Jewels of the Oracle in 1999, they deleted parts of the game, perhaps because those parts of the game caused problems on what was then "newer computers." In the Jewels of the Oracle game that I bought around 1999, the parts where you explored the cave to find the puzzles were deleted, though the puzzles themselves were still intact.
Incidentally, the Quicktime provided on the disk is version 3
The QuickTime on my Jewels of the Oracle disc was version 2 and came in a large box.
The copyright date on both the disk and the box is 1999.
I always thought there were two versions -- the old one and the new one with the exploration parts removed. But from what you say, and from the information on Mobygames, there are at least 4 versions.
I eventually bought a used copy of the original Jewels of the Oracle for Windows 3.1/95 (1995 version published by Discis). According to Mobygames, there was also a 1996 re-release published by Dreamcatcher. So along with my 1999 version and your 2000 version, that would make 4 versions (and there may be others). I don't know if the 1996 version still had the parts with the cave exploration or not. I would guess it did, and was similar to the 1995 Discis version. But the cave exploration was gone from the 1999 version.
I have tried this version on 2 separate WinXP laptops and the game can run right from the CD or you can copy the contents of the CD and click on LaunchJewels.exe to run it. There is no 'install' as such and Windows (ie. Registry) doesn't know the game is there.
Does it allow saving when run from the CD?
Does it prompt for where to put the saves?
I'm away from my Win7 unit right now so I can't test JOTO on yet, but will do soon and report back.
Let us know how it turns out.
Do you have 64-bit Windows 7 or 32-bit?
The Windows 95/98 version of the game may have had 16-bit code removed.
