DiskCopy + Basilisk II = Fail?

I have my Basilisk II setup running System 7.5.3 and I want to update it to 7.6.x. But DiskCopy seems to have gone on strike. Every version I've tried gives me this rubbish:

I'm using a Performa ROM, and there's a couple thousand choices for different models. Advice please?

This is the Disk Copy that you installed with 7.5.3? Was the virtual hard drive a pre-install that might be a PPC version? I don't know if that could matter for Disk Copy.

#3 Wed, 10 Jun 2015 - 10:24 68kMLA

Nope, it's not the Disk Copy that came with 7.5.3. And the virtual hard drive is a boot disk I downloaded. It could be PPC, I'm not sure how to check though.

Basilisk likely doesn't provide the shims to run it. Unsurprising, considering how (in)accurate Basilisk is.

IPalindromeI... I don't think Basilisk can't run Disk Copy (that's a pretty bold slam...). Juliet, it's the virtual drive you downloaded. Might be worth bothering to set up a drive yourself. (The inverted colors are apparently a function of the screenshot - this was the best I could do to invert them back.)

Disk Copy 4.x will have problems. Disk Copy 6.x is fine on Basilisk, but probably not anything that fiddles with the disk.

#7 Wed, 10 Jun 2015 - 16:15 68kMLA

Yep. I also have issues with 6.5, but that may be my build. The above is 6.3.3.

Actually you may have hit it on the head with version 4. I think the error I got may have been the same as Juliet's. So Juliet, I'd try 6.3.3 first.

Have you tried Mini vMac?

#9 Wed, 10 Jun 2015 - 20:12 68kMLA

I'm sure this is an ignorant question, but what do you need diskcopy for again? Is it that you've downloaded a disk image in diskcopy format and you want to boot the emulator from it? (To run an installer or whatever?) If it's a DiskCopy 4.2 image all you need to do is strip the header off it and Basilisk II will be able to use it.

Here's some tools for stripping off the header, assuming you don't want to use "dd" for it. (or are using a Windows box.)

Some .bin files only extract (or whatever you'd call it) with Disk Copy, right? Or would they generally also work with Stuffit?

#11 Wed, 10 Jun 2015 - 20:27 68kMLA

Uhm, a .bin file is a generic packaging format for transporting Macintosh files across channels that don't have any concept of seperate data and resource forks. You certainly might find Disk Copy images encoded in .bin format, but the .bin itself has nothing to do with Disk Copy. It is common, however, for .bin to contain Stuffit archives in .sit or .sea format.

I'm just conveying why I personally use Disk Copy on occasion. But also only because it's usually bundled. There are probably better programs for it.

I'd be mildly surprised if the offending version runs on vMac; BasiliskII and vMac use exactly the same method to communicate with virtual disks by replacing the floppy driver.

#14 Wed, 10 Jun 2015 - 20:57 68kMLA

Perhaps, but vMac can be configured with the Sony driver specifically so it'll work with Disk Copy.

I run vMac with the Macintosh II ROM, color graphics, and sound with the Sony driver. The sound really buggy, but it works well with software.

Which option are you talking about here? I see several options for tuning how the .Sony driver works with Disk Copy 4.2 images (IE, set it up to skip the header and update the checksum on exit) as virtual drives but that doesn't have anything to do with whether the running OS will itself will run Disk Copy 4.2 so far as I can tell.

I'm needing Disk Copy for the System 7.6.x install images I found. I'm needing to update the OS 'cause Toast seems to hate my setup and Virtual DVD-ROM/CD Utility apparently won't run on any version lower than 7.6. I'm trying to get a game CD image I found in .toast format to mount so I can install it and play.

#17 Thu, 11 Jun 2015 - 03:08 68kMLA

Problem solved! DiskCopy 6.3.3 is running great, and I'm now emulating a Color Classic II running System 7.6.

Now, do I want to upgrade to 7.6.1? That's the question.

#18 Thu, 11 Jun 2015 - 05:56 68kMLA

Just FYI, 6.5 probably works on Sheepshaver - on my 8.5.1 partition I get an error saying 6.5 requires OS 9.1 or later, but I've never been able to find a working bootable copy of OS 9 for Sheepshaver (really odd issue - this includes versions I have installed on genuine Macintoshes). Disk Copy 4.2 definitely works on vMac.

#19 Thu, 11 Jun 2015 - 14:53 68kMLA

9.1 and above requires an MMU, not emulated by SheepShaver.

IPalindromeI said:

Not yet, anyway.

It seems that would be the only thing SheepShaver needs to become a very nice, all around emulator for everything PPC from 7.5.x to 9.x.x.

It's probably not happening as the devs think it would slow it down, the devs are inactive, and SheepShaver is basically a very thin emulator.

My hope for proper PPC emulation is in QEMU.
