This game works with: Basilisk II, Mini vMac

This a a very quick and dirty version of robotfindskitten I did as part of RetroChallenge 2008 and updated in 2012 to include the NKI unification from The Mayan Apocalypse Edition of robotfindskitten.

Think Pascal source code is included.

Architecture: 68k

Tested on a Mac SE running system 6.0.5, iMac running OS 9, vmac and BasiliskII.

So I'm reading into this that while a compressed .img (a la DC6) is Apple's own animal, with dependent resource fork and all, that an uncompressed .img (also a la DC6) is very similar in format to .iso

Apology for assuming the .img wouldn't work

Should I just delete the *.img version?

@equant: No need, both uploads are fine. The raw ".img" upload can be used by dragging it into a Mini vMac window. It even boots up in Mini vMac OK. You could upload a ".sit" archive of the Disk Copy image if you want to add it to the page, but there is no need to delete what you've uploaded.

In response to SkyCapt's post:

VCD mounts .img's that have been stripped of resources?? They said VCD was for .iso/.toast/.cdr

The 1st paragraph on the Virtual CD/DVD page states; "The kind of image file types it can mount, may be .CDR, .DSK, .IMG (Disk Copy 6 .ISO compatible), .ISO, .TOAST, etc."

The "Disk Copy 6 .ISO compatible" part is the important bit. It doesn't matter whether a resource fork is present or not - it ignores the resource fork if it's present. As long as Disk Copy 6 compression was not used during their creation & were saved as a floppy disk image, Disk Copy 6 floppy disk images will be in a standard .ISO image format and may be mounted using the Virtual CD/DVD Utility.

Assuming there were even any resources in the first place, that is. Relevant ones, at least. In the case of the thread I linked to, the resources were important only because they contained compression-related information, which got stripped away. So an image like that, but without compression, supposedly wouldn't need the resource fork at all.

Outside the Mac world, I have seen thousands of ".img" files of diskettes for various computer games like the PC-88, X1, FM-7 etc. that used that extension, meaning not all ".img" files will have resource forks or be Mac-exclusive. Take ISOs or Toast files, for example: they require no further wrapping (they themselves do the wrapping job).

Turns out your ".img" is fine as is! I just used the Virtual CD Autotyper and then mounted it with the Virtual CD/DVD-ROM Utility without any issues. What program was used to create the ".img" file?

Normally, it needs some form of adequate wrapping (usually .sit, .hqx or .bin), because of the presence of resource forks, which other file systems and protocols don't take into account. On the Mac, IMG files are usually generated via Apple's Disk Copy 6, which often (always?) will require that to avoid permanent damage.

Also, above all, thank you for uploading your own version of this app!

As for other versions of rfk, I think most folks would prefer a separate page, though I personally think it's fine eitherway. What's really important is that the authorship of each version is made clear.

My intention was just to make my version available to people who might want to play it. Both versions are supposed to be the same thing, but different formats depending on what people want. I guess I had forgotten that *.img files get corrupted. Should I just delete the *.img version?

@SKyCapt ".zip" only if it Mac OS X zip and a few others. Else it won't protect the resource forks.

@equant, do you intend this page to be about rfk in general or just your version of it? Your first upload is damaged, ".img" can't be uploaded without first computing a 'wrapper' for it, for example ".img.sit" or "". Your second upload is I assume your "update" but both uploads are filenames "1.0.1" ?
