Kids Computer Part 2: Disc Image Magic
Posted on Thursday, June 16th, 2005 at 1:05 am under Mac Geekery, Tutorials.Last time we talked about the hardware needed for a simple kids computer setup. If you missed it go and read Kids Computer Part 1 and come back. Today we will be covering the tricky world of making disc images from game cds so they can be played from the computer without the need to load from a cd. The idea is to have all the games accesible from the desktop and be able to play all the games from the computer without the need of inserting cds. This is key for a great kids computer setup. CDs get scratched and lost. And CD players can be made to suffer at the hand of kids like my son Dante (read previews post).
This is Part 2 in a series for a kids Mac setup.
Building a Game Archive
An external drive might be useful to prep all your games so that you have a central archive of the cd images.
Know your Game CDs
The first thing you should do when you get a kids CD game is install it and try to figure out what dependencies it has, what kind of files does it have and what restrictions it has. Game developers make game CDs in many different ways. Some games are just one big Application that you can easily drag to the computer and play it. Other games require installation of supporting files. Some games, specially the ones made by the the bigger game companies, require that you physically have the CD inserted in the computer to be able to play it. If you install the game, eject the CD to find out if the physical CD is required or not. You will find that most games do require the CDs. But don’t worry, where there’s a will, there’s a way.
It’s all about Toast
Although Mac OS X comes with a very good Disk Utility Application, it will not convert all game CDs, specially the more complex hybrid ones. However, Roxio’s Toast Titanium ($59) will handle anything you throw at it. So, if you are in a budget, try Apple’s Disk Utility, otherwise invest in Toast if don’t already have it.
Step 1: Launch Toast
From Toast, select the Data Tab to build a CD of data. Then select Advanced from the drawer and select Mac Only. In this example we’re stripping out the PC version because we want to get rid of the autorun application that automatically launches when the disc is inserted.
Step 2: Add the Disc files
Click on “New Disc” to add a new disc to the list of files.
Insert the Game CD in the computer and navigate to choose the CD. Notice we see both the Mac and PC versions loaded. In this case, the one with the icon is the Mac version. Select it and press Choose.
Notice how the Game CD came in as a sub-directory of My Disc. Select all files from the game and move them up one level so that they belong now to My Disc and not the game.
Once All the files are moved up one level, double click the game folder so that we can copy it’s name, then double click on “My Disc” so that we can paste the game title and then delete the Game folder(not the renamed My Disc).
Step 3: Remove annoying behaviors
Delete the file .DS_Store. This file contains things like window attributes in OS X. This should prevent the disc window popping up when the disc image loads. This way the disc image can load transparently in the background.
Delete the file AutoRun. This is an invisible file that launches automatically when the disc is inserted. A lot of kids games have this to automatically launch the game when the disc is inserted. This will create a chaotic environment when you have ten different games loading at the same time each with their own AutoRun. Remove for peace and quiet during startup.
Step 4: Save Disc Image
Go to File > Save as Disc Image
Name that file however you please.
The almost final file.
From the finder, select the file and go to File > Get Info. From the Get Info window, select DiskImageMounter from the “Open with” pull down menu. DiskImageMounter comes with Mac OS X and is a background application that deals with the mounting and unmounting of disc images. Doing this will mount the Toast Image File in the backgound without the need to launch Toast. It also supresses all of the automatic window opening upon mounting when it’s a Toast image.
The final disc image.
It mounts, installs and plays perfectly. Look ma! no cds!
A note about Mounting CD Images. In Tiger, make sure you set the Verify Checksum to off in the Disk Utility Application. This will skip a very lengthy verification process. Panther users can use VerifyDI to turn that setting off. There are some CDs that are more picky than others. If you MUST open with Toast you can use ToastMount. Another option is to convert DMG files to ISO using Damage Isolation and open them with DiskImageMounter. In any case, good luck. Feedback is welcome.

Thanks for mentioning Damage Isolation. Hope you found it useful.

I tried this a few days ago with The Sims 2, so I wouldn’t have to have the hard copy with me where ever my laptop went. The only problem was that the game didn’t recognize it as the original disc. Does anyone know why this didn’t work? The disc is a DVD and nto a CD but I didn’t think this would really matter. I’m thinking it has something to do with some kind of copy protection but I wouldn’t put it past me to have done something wrong also.

jason, try locking the file through finder > file > get info. this fixes most issues. if not, use toast and make a cd instead of a data cd.
Jun 22nd, 2005 at 5:50 pm
Nice, but… can’t all this be done with Apple’s own Disk Utility, which comes free with every Mac and every copy of OS X? Why spend moeny on Toast for something like this?
Jun 22nd, 2005 at 6:18 pm
Jason,
You cant copy the sims onto cd as its more than 2Gb’s taken up… Try downloading the crack, its out there on p2p networks etc. Thats what im using and its quite good, I cant be bothered putting the disk in, its great for portability.
Cheers

The completely wrong way to make backups, IMHO.
Just insert the original CD, go to Toast, select Copy tab, and go to menu File > Save as Disk Image.
Q: Why not doing this with Disk Utility?
A: Disk Utility will not backup Hybrid images (Mac/Win/Unix…). It will only backup the Mac side of things and hence the game might be able to know it is not an original.
Once you have the file that Toast spits (named “something.toast”) first thing to do is lock it (menu File > Get File info… > lock) since just mounting it back will modify it (Mac OS X might and will add invisible files into it, for instance to remember the distribution of icons in the window). Locking it will prevent it. Locking it will prevent you to move it, too, so remember to unlock it, move, lock it back if you want to leave the file somewhere else.
You might want to try to convert the toast image (named “something.toast”) to a compressed and native to Mac OS X disk image (dmg). Sometimes it works, sometimes it does not. It has the benefit of saving a few MB and leaving the disk image in a not-writable state (and hence you will not need to lock it anymore).
To do so open Disk Utility, and then to menu Image > Convert… and select your toast image (named “something.toast”). Give the new image a name (without the suffix “.toast”), choose a destination (Desktop, for instance) and select “compressed” from the “format” drop down list. Leave encryption to none. Should it give you any sort of error, first try to mount the Toast image with Toast (by opening Toast, menu Utilities > Mount Disk Image), leave the mounted image there and try converting the toast image file again with Disk Utility.
From then on, should you try to mount the outcoming dmg with Mac OS X native mounter (by double clicking) you will get only the Mac side of the original hybrid CD, but if you mount the image with toast, or try to replicate the CD by going to Toast, Copy tab, selecting image from the drawer and dragging the dmg you will get a CD with its Windows side intact.
Should anyone want to enhance this guide or post somewhere else, feel free to do so. Do not give me credit for it, though, please.

Note: There are games that do require you do a disk copy like mentioned above. However, this guide focused on how to remove the application that automatically launches when the CD is mounted. If this is not done, every time the computer is restarted all these full screen game applications will launch at the same time.

Question: do you have to “install” the game first? (I imagine so). Also, can you then easily copy the image to other computers (make the image on Dad’s imac and copy for the kids?)
thanks

Would be great to have a list of games that “work” and “don’t”. Even better if people could post their Toast config files, would make a lot of lives easier. I am trying with Little People Airport tonight. My goal is to rid of the CDs and make the game app launch from the icon, not the group “window” with the launcher in it.

Hi,
Are those really nice icons in your desktop example from the DVD games (the ones that come with the movies, usually on Disc #2)?
Nov 21st, 2005 at 12:58 pm
what icons?
Nov 22nd, 2005 at 9:03 am
Sorry, from Kids Computer 1:

Nov 22nd, 2005 at 9:07 am
i made most of them since a lot of them are Mac OS9 games or just plain bad icons.

Andrew,
Could you give me the name of the software so I can back up my sims 2?
I’ve been searching for a while and have only found the windoze cracks.

Hi,
Very nice post and really cool.
Melvin:
Can you list me the title names of the kids games/educational series that are shown as icons? My kid just turned 5 and she at this age is a computer wizard and likes Mac more than Windows. I have Blue’s Clues Kindergarten stuff but would like to know what else is available for 5+ year olds?
Thanks.

hey guys im having a dowloaded cd image does it work on the same way??
i dont know if anyone will read this.. i mean u guys could all be dead?
Aug 8th, 2006 at 5:05 am
hey guys !!
ur all totoaly wrong!!!
why not just press utitles and then press mount disc image whit toast when u got ur cd image???
Aug 9th, 2006 at 5:33 am
You can mount the image. But how does a kid launch the game? Ideally it is one icon-click, which is why Iused Automator to Mount, Pause, and Launch. Typically the launch icon is embedded within the mounted image.
BTW I have successfully done the non-CD thing with these KIDS games:
1. Reader Rabbit Baby
2. Reader Rabbit Toddler
3. Reader Rabbit Kindergarten
4. Little Bear Rainy Day
5. Reader Rabbit Dreamship Tales
6. Kelly’s Pet Parade
7. BArbie Pet Rescue
8. Little People Airport
9. Kid Pix 3 OSX
10. Blues Clues Goes to School
11. Dora Animal Adventures
12. Dora Lost City
Couldn’t get it to work with Mac versions of:
1. Arthurs Sand Castle (no OSX)
2. Arthur’s Pet Chase (no OSX)
3. Barbie Swan Lake (copy protection – works with CD ok)

Hello,
I just found this excellent resource. Thanks.
I too tried to make a no-cd image for SIMS 2
and it does not work. The image mounts and the
program runs from the image.
Then I get the message to insert the original disk.
Has anyone yet solved this previously asked issue for SIMS?
Thanks very much.

I have tried this technique with my Age of Empires 2 Gold CD, but after I had mounted and double clicked on the Game file, it came up with “Age of Emprires…. requires at least 2mb of free space. Free up some space on your local disk then re-launch Age…..
Yet I have plenty of space on my g5 imac.
Any help would be appreciated.

HI,
I`ve seen you guys talk about The Sims 2. My problem is that I`ve downloaded my game on a regular mac os x mini, when I click on “The Sims2″ icon/widget,
it says I need to clear up/make space on the “local disc” this has been driving me NUTS! I`ve looked on google,The Sims 2 website and apple.ca,but still have NO clue whatsoever where I can find the “local disc” and how to make room. I`ve checked how much room is left on my hard drive it`s-22.26Gigabites and has a capacity of 37.14 Gigabites,so I don`t understand. Aswell the night before I played the game from 9:00-2:23 am (I really love the sims) and so why would it work then but not now?PLEASE HELP ME IM GOING INSANE!!!!!!!!
Dec 25th, 2006 at 8:48 pm
Confused,
I too was having the same problem….see if this helps…

Automator solves all of this. Write a script that opens the Image file. Then add a “launch application” icon that is sourced from the mounted disk. that’s the secret.
Dec 27th, 2006 at 7:32 am
i am not sure why it will tell you it’s running out of space. but i would suggest running Yasu, a system maintenance utility. this app clears your cache, runs the mac os maintenance scripts and clears logs. fixes a lot of my mac issues.

err yeah good product
Jan 2nd, 2008 at 10:23 pm
Great set of articles and still relevant. Two questions….
1) Was there ever a pert 3 and if so where can I find it?
2) Did you ever locate the flash launcher from the kids computers at the Apple store?
Thanks

Does anyone know how to make a .toast that works for Sims 2.
