What he says is still true in that the current format (DSK) has no concept of sector addressing. SimCoupe does _need_ an additional format of some sort to be able to describe every possibly physical disk that works on a real SAM. I never did track down a definitive spec for the Amstrad format(s) (anyone know where I can find it?). I got to the stage where I was looking through source code to try and work it out, and only found out that it stored status values for certain actions, which is something I do too. If the format is sufficient to cover the SAM floppy controller (as there are things that can be done on the Amstrad that aren't possible on the SAM, and possible vice versa) then I'd agree that it's best to use that. The new format is certainly not set in stone as nobody else has a version that uses it, and only Aley has seen a/the proposed format described, so far. I have a few disks (Lemmings, Prince of Persia, ...) in that format that I use to play them, but they can easily be converted if the format is changed. Si
