I recently tried out a program called "nero burning rom", it had one feature I really felled for. It came with a program called imagedrive, which I really liked.

What the program does is this, upon installation it adds one extra cd drive, "fake", and with the program you can mount iso files to that drive. Windows acts just as if you have inserted a cd, meaning that autorun will start or that the media player starts if the iso is a copy of an audio cd.

The bad thing is that it doesnt work with .iso files, but with a similar format of its own.

I would like to ask you guys, do you know any programs like this?
Or could you tell me HOW complicated this is to do?

I get the feeling that for a cd-driver programmer this would be a piece of cake, just reading a file for sectors requested instead of tricky device vxd stuff, but I am not such a programmer...

(I know some of you anti-copying guys might dislike this program, but I think it has some legal use dont you?)

anyways, all help is greatly appreciated

Doing a "software simulated" block device driver will sure request a VXD esp if you want to foul mediaplayer and other programe to belive they run/read from a CD-ROM

this sure can be done (it was possible from the CP/M era) but its not very easy

Besides very good knowledge of ASAPI and SCSI devices/commands is required in order to get raw sectors from a CD-ROM. Contrary to popular belief readin a CD-ROM for data is not a piece of cacke,

Data is stored on a SPIRAL and because of this it very hard to reach a random sector (much harder then the HDD cylinder/head/sector stuff) Audio Data is even more tricky as a 2 second gap separates data and one must recalibrate by checking stored music samples from time to time

it can be done but its not a trivial or funny job

besides it will not fould most copy protection schemes

If you have a standard ISO file (raw CD image), the only hard part
of writing the emulation would be understanding the windows interface
you're trying to plug into. In the case of windows 9x, this would be
the IFS (installable file system) subset. I can't say I have any idea
as to how it works, as the 98ddk is a very messy pile of junk.

Apart from that, it shouldn't be too hard. I would be very much
surprised if the internal requests aren't simple block requests, with
a logical block numbering, where it is up to the CD driver to translate
it to physical sectors, and up to the CD drive to access the "spiral CD".
ANything else would be totally bong-brained. But of course, we all
know that microsoft have made some truly wonderful APIs and subsystems,
and some other APIs and subsystems that suck ponder water.

Daemon tools is what you need. It will let you mount a CD-ROM image (different formats) as a real CD. If it is legal or not depends only on you.

Daemon Tools are free, but paragon CD emulator is much better.
It allows you to compress images, convert between a number of
format, and even export it's own compressed format to a ready-to-burn
ISO image. It's very practical to have MSDN on my harddrive this way.
It's somewhat smaller than a full install, and at least as fast.
