So, why don't some clever programmer create a perfect-clone proggy. I made protected disks in the past, there's several techniques. Like non-formatted sectors, extra tracks etc. Dunno much about emulation, but would it be THAT hard? Maybe it's the PC-diskdrive that's the problem? Else we could whip up a disk images system on MSX itself using a HD for storing that image
hmm....
It is possible to write protected/non-formatted sectors with a pc-diskdrive, so the reading part would also be possible. Dunno too much about this, but that would be kinda logic.
There're already several great clone tools for PC. Imagedisk and recently Samdisk are the most advanced and they can clone almost faultlessly any disk. Imagedisk only work in a pure DOS setup and Samdisk can work with modern OS. The later can also copy several protection schemes but mostly from Spectrum and Amstrad world. I've used it to clone MSX (standard) disks and it works.
ro: this is exactly what Wouter's tool does... it can dump disks with all known copy protections that exist on MSX.
Cloning standard disks is not an issue, but cloning disks with advanced copy protection schemes is!
Nice... Gonna give Samdisk a try !
Clone as in making a copy to another physical disk?
or do you mean making a disk image usable in emulators? The latter was the point...
It lets me think that in some cases the trick is to copy first the original disk on another disk before making the image of the second disk in stead of the original disk.
That will definitely trigger any serious copy protection...
Hmm it seems that Sandisk nor Imagedisk can NOT create .DMK images (only RESTORE .DMK )
Is there a PC tool that actually can create a .DMK image from a floppysdisk ?
I don't know any, but as I said, Wouter is working on an MSX tool that can do it, which I am testing...
So again: which original disks should I try still? So far everything I tried was (in the end) dumped successfully and could be run on openMSX.
