I am unable to INSTALL my original D-Generation (3.5" 720 MB) game.

Through DOSbox or underlying WIN XP Pro, it doesn't recognize the original disk from the DOS install program (install.exe) off of the disk.

I had had the same problem with QIX, and was able to find a downloadable version of QIX at Moby Games.

No such luck with D-Generation.

Any ideas? Solutions?

P.S. It was distributed by MindScape, which was bought by The Learning Co., which is now owned by Broderbund.

I think most games from The Learning Company used a physical disk protection.

This game was put out by "The Software Tools, Inc.", and distributed by MindScape before The Software Tools, Inc. was bought by MindScape, and before MindScape was purchased by TLC.

However, it probably has some physical disk protection of that era. BUT, I have the original disk, (as well as the 5-1/4" floppy disks!), the original box, manual, etc.

So, disk protection shuld not be an issue.

well DOSBox doesn't support those lowlevel calls unless you imgmount the drive. and the you might even have to boot a real version of DOS.
Windows XP command prompt doesn't do them either I suppose (that dos is emulated as well)

Can you please explain "imgmount" ? of the floppy a:\ drive?
I've not seen that term anywhere in the help/FAQ/DOCs.

Make the floppy image and mount it. Read README and see the DOSBOX Guides forum.

Here's my take (from reading the README):

- - - - - - - - - - - - - - - - - - - -
mount a a:\ -t floppy
IMGMOUNT DRIVE a -t floppy
- - - - - - - - - - - - - - - - - - - -

Correct?

Not exactly. You need some program for creating a floppy image (it will probably have .img, .ima or such extension). Then you must mount it with the imgmount command under DOSBox.

PS - I think there are freeware programs to do images. Just Google for them.

Use something like WINIMAGE:
1. Insert your floppy disk and select READ DISK
2. Select SAVE AS and select the "IMAGE (IMA)" type/format.
3. Make sure you name the file ?????.FLP
(Necessary? or should it remain ?????.IMA ?)

Then in DOSBox:
IMGMOUNT a ?????.FLP -t floppy

Correct?

The only question is, since there are two floppy disks, would I read both disks and combine all of the files into one image?

Thanks!

P.S. Got an error reading Disk 1 of 2, but I I did IGNORE and will try it, anyway.

Disk error on track 39, head 0
Address not found
The drive cannot find the sector requested

No - you make 2 images. Call them Floppy-A.flp and Floppy-B.flp. In DOSBox you mount them as

IMGMOUNT A Floppy-A.flp -t floppy
and
IMGMOUNT B Floppy-B.flp -t floppy.

Inside DOSBox you should now have 2 drives, A: and B: containting your 2 original floppies.

Either the disk is bad, or it is part of the copy protection.
In both cases you're most likely out of luck. Maybe the
floppy works better in a different floppy drive, or some
old dos floppy copier (hdcopy, vgacopy and the likes) works.

It's part of the copy protection.
Without it, the install program in DOSbox acts like before,
and keeps telling me I need the original disk.

I will try one of those other two (hdcopy or vgacopy).

Thanks. I tried both VGACOPY & HDCOPY and both found an error (old copy protection) in track 39 of Disk 1.

I have a question regarding trying to install a game using IMGMOUNT which is on two disks.

If I try:

imgmount a disk01.ima -t floppy
and
imgmount b disk02.ima -t floppy

I get an error in dosbox.
"DOSBOX has encountered an error and needs to close. We are sorry for the inconvenience."

I only have one floppy drive on my system.
Nothing is assigned to the real b:\ drive, if that has anything to do with it.

So, if I leave off the imgmount for "b", and only run imgmount for "a", then when the install finishes with disk1 in drive A, it looks for Disk2 in Drive A.

How do you do that with DOSBOX? I cannot interrupt the installation to now install the Disk02.ima image file onto drive a using imgmount.

Though I would still like to know how one can possibly do this (above), it is now a mute point in trying to get the game to work. Someone sent me a file that will allow me to install the game. AND I copied all files from both disks into one directory, mounted that directory as "a", and ran the install, wotked just fine.
