Images to disk ( PASTI to real ST floppy )

Postby nativ » Sat Feb 18, 2012 7:32 pm

Hi all,

I haven't really used PASTI before is this possible? Writing a STX pasti file to a real floppy?

Is it possible to covert between ST > MSA > STX on PC?


Thanks

No on both counts I believe - certainly not writing back to floppy. If you want a low level floppy imaging tool that can write back to floppy, then Kryoflux is currently the only product I know of that will do this.

I can't see any benefit of converting to STX from ST/MSA - what's your idea?

The idea would be to enable the repatriation of Atari software. There are a lot of games available in the PASTI archive format and it seems a shame that it isn't easy to use them on an ST.

I also means that the 'archives' that are available could be amalgamated rather than needing a PASTI archive a ST / MSA archive and a raw file format archive, the last one is sadly missing a great deal, especially without Climatics as I think a lot of the files were up there in ZIP and not compressed.

What is so special about PASTI that it requires hardware?


Thanks Dal,

Pasti isn't a standard sector-level imaging format. It includes timing information so that the disk image behaves within an emulator (only STeem and SainT at present) in exactly the same way as the physical would behave in a real machine.

The point of PASTI is to create images of copy protected disks that can't be written without specialist hardware - the kind used at the old duplication houses back in the day. The whole point of this protection was that it was not possible to duplicate the behaviour required to copy disks on consumer hardware (like the floppy drives and chipsets in Atari/Amiga/PC/etc.

Best to have a read of:
This

There is speculation that PASTI images created with the discovery cartridge have the necessary information required in order to recreate physical disks (again using the DC I presume), but there aren't many of these images around and I haven't seen any evidence that it has been done.

ok, kinda like the system 'GAME' the highstreet retailer had, where they make a disk for you when you buy it.

that's a shame it's not more usable.

How about a ULS type PASTI loader on the ST side?

That sounds like a great idea. Far beyond my knowledge as to how feasilble It might be.

Maybe Ijor or someone else with low level PASTI knowledge could chime in here?

This could only work for image content that uses the OS for accessing the disk, working in a similar way like PP's Image Runner.
For DMA loading stuff and copy protected content: no chance, IMO.

The tears are welling in my eyes again, I need twenty big buckets to catch them in, twenty pretty girls to carry them down, twenty deep holes to bury them in.
