Apple IIGS emulators -- questions

Now that I feel that the DOSBox issues and playing the games on Mac is getting someplace, I have some additional questions.

My family owns an old Apple IIGS that we've had since I was in kindergarten. This was how I first heard about King's Quest. My dad used to play the games with me on that computer. The computer still works -- I turned it on a couple weeks ago.

My new computer is a Mac, and so that reminded me of the old Apple IIGS -- which I hadn't touched in over 10 years. Although I went through King's Quest 1-4 on that computer, it had been such a long time that I forgot the differences between those versions and the versions that were on the King's Quest Collections that I have. The differences seem to be mainly with the sound -- music and sound effects seem to be better on the IIGS.

I had come across a video of someone demonstrating the music that was only available on the GS. Hearing that music and sounds again made me want to play the GS versions. After some research online, I got ADT pro and used that to connect the GS with my Mac, using a serial cable and an adapter that connected the USB port on my computer with the serial cable.

I then tried copying all of the original disks from the GS to the Mac using that method so that I could play the games in Apple IIGS emulators. All of them seemed to work (I just turned them on and checked to see if they would play in the emulators) except for King's Quest 1 and King's Quest 2.

When I looked at the original box cover that the King's Quest 1 came with, I saw that it wasn't actually the GS version, but rather the IIe version. That was fine...the GS played it. The problem came with the emulator. The IIe version came on 5.25 floppies instead of the 3.5 floppies, and it seems that the disks were copy protected. So, although it copied the disks and sent it to the Mac, the disk images won't play in the emulator. Does anyone know how I can fix this?

The problem with King's Quest 2 is that Disk 1 seems to be copy protected as well. This was the IIGS version, and it was a white disk. I thought that was strange because all the other GS KQ disks were blue, but it is the original disk from Sierra.

I tried playing it on two emulators -- Sweet16 and Kegs. King's Quest 2 disk 1 caused the emulated GS to freeze. I searched for disk images of King's Quest 2 the GS version, and all the ones that I came across online also caused Sweet16 to freeze...so it's got to be something to do with the copy protection on the disk.

I checked to make sure that the disk actually played on the real GS. It did. However, there is a message that came up right after it loaded that said something like "if you want to play a backup copy, insert it now" or something like that.

With some help from other people, I got a disk image of Kings Quest 2 disk 1 to play on Kegs -- the same disk image that caused Sweet16 to freeze. On Kegs it gave me a message after I mounted it that said something about it being 0 instead of the expected number. It mounted and played anyway.

When I tried playing the disk image that I had copied from my disk, it mounted in Kegs with the same 0 warning thing. When I tried playing it, in the spot that the message had come up telling me I could play a backup copy, it told me that I needed to insert the original disk even though it was the original disk image that I was using.

The disk image that I'd gotten on the Internet didn't have that message -- it just went right to the game. Still, something must remain from the copy protection or it wouldn't cause it to freeze in Sweet16.

I don't mind playing the game in Kegs, as I couldn't get any 5.25 disk image to play in Sweet16. I think most of my 5.25 disks were copy protected (the only King's Quest game that we owned was on that size was KQ 1, but I had other games on that size disk), but I found disk images online that would play on Kegs.

Anyone know anything about this? I'd rather be playing on my actual disk images rather than ones that I got from the Internet -- but it's still the same game, so I guess it doesn't matter that much. However, I couldn't find a disk image for the version of KQ1 that I had (the IIe version).

This isn't a huge deal, but I do like playing the Apple version of the games, as those are what I originally played, and the sound and music is better than on the Dos versions.

The early AGI games had the infamous CPC disk copy protection that faked a bad sector to hide part of the copy protection. This causes problems on modern systems that don't give the low level access that this copy protection requires to work. You can read more about it here. There was the old SUP program to "deprotect" the games on PC. I am not sure what they did for copy protection on other platforms. I don't allow links to abandonware sites to be posted here, so you would need to Google for it, but the best I could suggest is to look for copies on such site to see if you can find ones that have already been cracked.

:) I found disk images to everything except for the KQ 1 Apple IIe version. I'll try to look more for that later.

Thanks for the information on copy protection. I hope I can find an Apple IIe version...and I wish I could get the King's Quest II disk images to play with no problem on both emulators that I have. I wish I could get my own copy to play on the emulators. Sigh....I doubt I can deprotect the file myself...since I don't really know what to look for. I'll definitely read about it, though :)

Hmmm.....it sounds like they would have done something similar with the Apple disks, but those wouldn't be the names of the files. I wish that the links on that page would work on my disk images :( Sigh.....Sierra isn't really around anymore to see if they have that sort of thing for those disks, and I doubt that the company that owns the King's Quest copyrights knows how they copy protected those disks, since Apple II's aren't around anymore. I doubt they used exe files.

Obviously, some people have figured it out -- they were able to get disk images up online....but they must not have completely figured out how to deprotect the King's Quest II disks.

I really would like my originals to work. But at least there are disk images that I can play online :)

So King's Quest II disk image that you found online doesn't work either? If it's the site I'm thinking of, the problem is probably the online emulator is quirky, but KQ2 does work. The button to mount disks doesn't work. You have to right click and do it manually. You can also download the disk images from the site, too, and run them in KEGS or Sweet16.

You can PM me if you need anymore help. IIgs games and emulators are one of my specialties.

The King's Quest II disk image that I found online behaves the same as my copy of King's Quest II disk 1 -- it causes the Sweet16 emulator to freeze.

However, both my disk and the image I found online work in Kegs. My disk still has the copy protection thing in place, so it won't let me play the game. It asks me to insert the original disk at the same point that the original disk on the real Gs gives me permission to put in a backup copy. Kegs also gives me a message about it being 0 instead of the expected whatever.

However, while the image I found online still gives me the message about it being 0 instead of the expected number, at least part of the copy protection is gone. It does not prompt me to put in the original disk, but instead goes right to the game. Again, this is in Kegs because the image doesn't work in Sweet16. Can you get it to run in your copy of Sweet16? Maybe it's just my copy of Sweet16.

I tried getting that specific image from different sites, but all of them behave the same way in Sweet16. All of them cause the emulated GS to freeze up. There must be something in the disk that causes that reaction in Sweet16. I don't know whether it's an error in Sweet16, or if there's something in the disk itself. The copy of my disk did it, and so did all the images I found online from various sites.

Oh...I noticed I couldn't change disks on that site. I didn't know that I needed to right click it. I gave up trying to play games on that site becaue it wouldn't let me change disks.

Maybe it's a problem with Sweet16? I never used that one. Can you run Classic or System 9 on your Mac? You could try Bernie ][ the Rescue. It's an old, but good emulator. I doubt it works in OS X though.

Nope -- I have OS X Snow Leopard, and it doesn't allow me to run Classic or System 9. If I try to run something that is Classic, a message pops up that tells me that Classic isn't supported.

This is the first Apple computer I've had since the Apple IIGS, so I don't have any of the older operating systems. :(

I e-mailed the developer of Sweet16 about the problem. The person hasn't gotten back to me about it.

Kegs does work with the disks, but it just gives me the 0 instead of the expected message...but the disk images load fine.

What do you mean? Could you show a screen shot of that?

It would be a pretty old Mac, anymore that could run Classic mode or a pre OSX Mac OS. Both require an old PPC.

Yeah, I still have my old G4 for the sole purpose of being able to run classic programs. Which reminds me, I wonder if running OS 9 in Sheepshaver and running Bernie in that would work.

Sure -- now that I know how to do that.

I just found out how to do this yesterday -- I'm not sure how to post it on the forum...but let me go load Kegs and show you what's going on.

I made a movie of it -- I could post it on youtube, or I can see if I can post just the error message that I get when trying to load the disk. I tried loading my Black Cauldron copy on Kegs, and I got the same 0 instead of 800 message displayed, but I know that my copy works.

Not really sure what's going on -- the disk images work fine in the emulator -- but I also taped me trying to use my copy of KQ 2 disk 1 to show what happens when I try to use it in Kegs. Then I used the online copy of it that I had, and it works fine. Hmm....I wonder....I wonder if the online copy could be used as the "original" disk.

So...shall I post it on youtube or should I post just the image of the error on the forum somewhere? Not sure how to do that -- but I can see if I can figure it out.

Wow, that brings back some memories- I remember selling G3's when they first came out in the mid-90s timeframe. They were hot stuff. :)
