what if you mount a: or b: in VFD? maybe your OS has sth against y: for floppy (where have you got the y: idea from? 😉 )

um... I just have VFD set to load the floppy as y:\ .. I have tried it as a:\ using

mount a a:\ -t floppy

but these games just freeze during the floppy check (please insert your original disk into a:)

I mean I got thexder to work by just downloading it form a abandonware site... (yea i know) but the point of the thread might have gotten confused... . .

Q: Isn't imgmount ment to be able to load *.IMA files using the -t floppy? To load floppy disks as IMA files?

>if I remove the "-t cdrom"
?

if I try the command with out the "-t floppy" at the end I get a different error message... I "think" cause dosbox defaults to something replacing -t cdrom.. I dunno I just tried it.

isn't ima a compressed format? try converting it to img

Thexder's copy protection uses illegally formatted sectors, so you may need to crack it even if you do get an image of it to mount properly in DOSBox.

as far as i remember imz its ima/img compressed =)

In case anyone else runs into this problem and this thread, just rename the ima to img... I don't know why dosbox is locked into img and not ima when they are they same format...

I've never had any problem mounting or booting floppy image files with .IMA extensions, and there is nothing in the DOSBox code that cares what the extension is; however, I suppose it's possible there could be an issue with the host OS. In any case, I recommend taking the proposed solution with a dose of skepticism.

In my collection of floppy images, an IMA extension denotes a readable FAT file system, and an IMG extension means no file system. I did this because IMA is associated with WinImage on my Windows OS, and not because it holds any significance to DOSBox.

Sometimes DOSBox can't handle floppy image(s) injected ancient boot virus.
Maybe try to scan it by older antivirus program(s) first.
