Title: 3DO Demo Disc
Post by: Anthony on July 12, 2007, 12:04:34 am
I recently got my hands on a 3DO demo discs called "Sample This!", which contains 2 demos of games made by TFB:  The Horde, and Star Control II.  I tried to make an ISO of it, but it would not even start, and simply abort.  I resorted to make a binary image of it, and the unCDROM program still would not read it:

Looking for 3DO CD-ROM disc header in image: "samplethis.bin"
Test of sector: 317864
        File: "samplethis.bin" is not MODE1/2048 3DO CD-ROM images

I am aware that it is intended for ISOs, but I can't find a way to make an ISO from this CD.  I used PowerISO to create the BIN file.  I never had this problem when I was making an image of the original Star Control II full 3DO cd.

Does anyone have any ideas around the demo disc

Sorry, it was a false alarm.  I found an alternative program called MagicISO, and it copied the CD without any problems.  I searched for the problem on Google, and I didn't find much help.  I'll let you all know how the demo disc goes once I start playing it some more if any of you are interested.

I don't know why it didn't work when you tried to create an ISO image.
With bin/cue, the .bin file can contain different formats of CD images, and the .cue file specifies what format is used. Unless I'm terribly mistaken, the MODE1/2048 format gives you a .bin file which is actually the same as an .iso file.

If you tell your ripping program to rip the CD-ROM in raw mode you probably get a MODE2/2352 .bin file, which is probably what you did. If you can rip in cooked mode, you'll probably get a .bin file which you can use. If you can't get that to work, you should be able to find a program to convert your MODE2 .bin to a MODE1 .bin (or iso) file.
