"I found a working copy on eBay. It’s heavily copy protected and all my imaging tools failed. I was, however, able to copy nearly all files—except one—onto a blank DiskDup+ disk image. The one missing file had the bozo bit set, was invisible, unreadable by Fedit, and had a filename consisting entirely of non-ASCII characters. Despite this file’s omission, this image feels like a pretty good capture of the essential game files. I leave it here for a better person to defeat the copy protection and get it working." — jkheiser

The first file is a bootable, ready-to-play DiskDup image, with the protection disabled by barberd's reverse-engineering work detailed below.

The second file is a flux-based disk image (A2R) of a protected original disk captured with an Applesauce FDC. Its contents can be viewed using the Applesauce client software.

The third file is the A2R flux image converted into WOZ format, suitable for writing back to another floppy disk using an Applesauce FDC. Future emulators will also be able to make use of this image.

"The fourth file, STKobayashiAltModded.sit.bin, is a cracked version modified to no longer crash upon startup. It was tested working on System 6.0.8 and 7.0.1. See comment below for details on the modification." — barberd

Note the two different manuals. One is the mission guide that has the lore and in-game backstory, the other is the procedures manual that outlines the actual mechanics of gameplay.

Maybe, but I doubt it; the code just doesn't seem that complex. Kinda like the publisher had them add in the copy protection at the last minute. But really the game is so bad it wouldn't really make a difference even if it did. The program is kinda admirable if you look at it as an artistic experiment in a new medium (telling a story through a video game)...but its just horribly painful to play. Kinda exactly what you'd expect with a book publisher making a video game in the mid 80s though. Smile See this review that says the player interface/experience makes it probably the worst adventure game ever...which after trying to play it, I kinda agree with.

Nice work, barberd! Good ol’ 468470 to the rescue once again.

I wonder if there are any other copy protection booby traps lurking. Maybe the game will detect the NOP and make Spock start murdering everyone.

I reverse engineered the executable to the point of isolating the crashing code and removed it, replacing the area with NOP (no operation). The code in question is located in segment CODE3 from address $102 through $10A. The game now starts and is playable. I've uploaded it as STKobayashiAltModded.sit.bin.

@MrA2001 Most likely no. I think there is only one Mac emulator that can run .woz images, and it’s Windows-only. What emulator are you side-loading onto your iPad Pro?

Can this be opened / played on an iiPad Pro?

I just confirmed the flux images are CDEF-free.

I've replaced the CDEF-infected DiskDup image with a clean (but still copy-protected and unplayable) one made from my own original disk. However, I lack the means to inspect the A2R and WOZ images, let alone replace them.

The WOZ-format disk image I just added to this archive can be written back to another floppy disk with an Applesauce FDC. I verified playability with a 4-megabyte Macintosh Plus.

It bombed in DiskCopy 5.5 the same as the original diskette. Infernal copy protection!

DiskCopy 8.0 has been added to the Disk Copy 4 page. It also professes to duplicating copy protected disks. You may want to try this. Tho' the comments by slomacuser on that page aren't encouraging.

One other thing I want to mention: Copy ][ Mac 7.2 was able to duplicate this game to another floppy without error. The copy boots and the game starts to run, but then it dumps you down into the MiniFinder. I was unable to image the copy, either. It bombed in DiskCopy 5.5 the same as the original diskette. Infernal copy protection!

Ah bummer. Thanks for looking at it, all the same.

@MikeTomTom I tried 5.5 and it failed as soon as imaging began.

@jkheiser: Thank you for this very rare find.
In your imaging tools, have you tried Disk Copy 5.5? 3rd DL on that page. This is a user-made Disk Copy clone, based on leaked code of the Disk Copy 5.0 beta. It claims to be able to copy (and image) copy protected media.

Not having copy protected floppy disks, I haven't been in a position to test this out properly, so am curious and hoping you might be able to, if you haven't already.

Just an FYI for people who are looking for a copy: The ISBN for the Mac version of this is

ISBN: 0671628615

This is important because there were about six or seven different releases of this title for various personal computer platforms, and a lot of sellers on Amazon, abebooks, eBay etc, mix up the versions and aren't clear about which is which. Good luck!

The screenshot is from the Macintosh Garden Wanted List; I was able to get this for cheap because it did not include the game disk, so I've scanned and uploaded the manual and will hope that someone else may find the disk itself...
