EMT4WIN for Windows

[Chr$]

On Dilwyn's site, here:

http://www.dilwyn.me.uk/utils/index.html

There is a reference to a program called EMT4WIN which is apparently able to make raw images of QDOS floppies from windows.

The link is dead.

Does anyone have this or some other program that can create img's from windows?

Incidentally, I've tried making images on a real QL and it seems to have a problem with line 1100 of the MakeImage_bas file (part of FDI). The line is:

Code: Select all

1100  LOCal a$,s$,d$,fileName$,tracks,sides,sectPerTrack

Syntax problem, I suspect there may be an easy fix? Edit: hang on, perhaps I need to LRESPR the FDI1driver_cde first!

Ooo, found it here:

Will see if that works.

Another edit: It did! I created an image and Qemulator was fine with it.

Create floppy image from within QPC2:

Code: Select all

100 OPEN#3,'flp1_*d2h': REMark *d2d for DD
110 OPEN_OVER#4,dos1_temp_test.img
120 FOR track=0 TO 79
130   FOR side=0 TO 1
140     FOR sect=1 TO 18
150       GET#3\65536*track+256*side+sect,a$
160       BPUT#4,a$
170     END FOR sect
180   END FOR side
190 END FOR track
200 CLOSE#3,#4

Of course one can also mount the real floppy as FLP1 and an empty image as FLP2 and copy files over etc.

Aha, that seems to be promising so far. Just trying it with a DOS HD blank disk - that was fine. I did have problems getting QPC2 to work with floppies at all, but now I have discovered the trick with starting it off with a DOS formatted disk. Just tried to image an old DD Merz program and it reports 'Medium Check Failed'. The same disk also failed using EMT4WIN, is it due to some kind of protection?

If I remember correctly, EMT4WIN has problems with floppies that have too few physically formatted tracks. I had a few disks that had been formatted with less than 80 tracks. I think QPAC2 was one of them. If you do a DIR and the total sectors is less than 1440, then this is one of them.

I think the idea was that it made duplication quicker, if you only partly formatted the floppy

You can create floppy images from within the FDI program. I think the command was MAKE_FDI.

Yes indeed, the problematic disks have all been formatted with just the right number of tracks required for the data, so that would explain that. Thanks for solving that one!

I will look further into MAKE_FDI.
