I understand that they are ripped Acorn disc images for PC emulators, i was just wondering if there was any way to 'Unrip' them back so that they would work on an acorn.
Contact me at eddy@drownedinsound.com
Or reply to this post
Thanx,
eddyosaysyo2

[Update]
After a lot of research, I found out about :
Darren Salts method which almost works, ArcImg which doesnt work on XP, !DImager which i cant get working, ArcEm, and Archie.
Help me!

Found out how to!
If anybody else wants to know (as its extreemly annoying trying to find out)

Make sure your disc is formatted ADFS 800k (D), open up a command prompt and type the following.

*BASIC
>END=&1A0000
>DIM buf% 1600*1024

For each floppy image:

>SYS "OS_File",16,"image/adf",buf% TO ,,,,L%
>SYS "ADFS_DiscOp",,2,0,buf%,L%

Eject the disc, put it back in and it should have the correct files on it.

If the disc image is 1600k then do the same with a ADFS 1.6Mb formatted disc, but Dismount it before attempting to open it.

Many thanks to Darren Salt of YMBJ software for this method.

Hi,

Sorry about ressurecting this zombie thread, but I'd like to add some notes for other people who may stumble upon this from Google like I did. smile. I had a couple of problems getting it working, but a little research and it all works fine. Many thanks to Darren Salt and Eddy Wilson for the original post.

1) Before you do the basic command, enter into the directory where you disk image is.

in my case, it was:
* DIR ADFS::Test , Where Test was the label on my floppy.

2) Caps matter. As a programmer myself, I should have realised this *thwaps head*. Windows has spoilt me!

3) In the first SYS line, "image/adf" is the filename. Make sure it matches what you have called yours, (or make your image file match this).

I know it may sound obvious to many of the Acorn veterans around here, but it helped my nostalgic self and my *ahem* 'new' A3020.

So adf's are recognised by the operating system? I seem to remember reading about them somewhere in the PRM.

Correct. They're exactly the same format as floppy discs use, so if you can write them byte for byte to a floppy (like the ADFS_DiscOp call does) then you should be able to transfer the data to a real disc.
