Re: kryo2apd

Hi Jon, I'll try and have a look tonight. Looks like I did something lazy with an array as it puts the APD file together. I'm guessing we're not expecting any FM tracks here so the -f option should be fine. I'll have a look at the original files and see if I can work out what's going on and where. d.

Re: Protection methods in use

Thanks, Will do! I've been having a bit of a chat with a few people. It seems that although IPF is capable of storing FM data, no one's actually extended the container to do so and the library to read them won't handle FM (or GCR) encoded data either - yet, although that yet was at least 12 months a...

Re: Protection methods in use

Thanks, that's really useful. With kryoflux streams it should be possible to use these to help put together IPFs. I was just trying to find the programmer's reference which you said was on the FTP site, but I don't seem to be able to see it anywhere?

Re: SquishFS (SFS module) breaks on later versions of ADFFS

Hmm. No, those ones have no FM tracks in, those are just the DD streams. They come in at under 900k, albeit gzipped, by my reckoning?

Re: kryo2apd

Sure. Is there a website yet for hosting this? I'll attach it to the post otherwise.

Re: kryo2apd

New version uploaded, can specify -f to omit the FM stream (which always has false hits) if you know it's not required. Reduces the size of the apd massively.

Re: AutoVIDC 2.09

Paul, being the clueless sort that I am, I note that this does do things on machines which have the relevant clocks already (e.g. A3020/A5000), but what are the things it does on those machines? :D

Re: CCITT CRC

Hmm.. Just having spent a few hours bodging this in and out of java and a few iterations, it seems that using the raw fm/mfm with clock bits intact in words or bytes (it was easier to deal with things a byte at a time in the end) doesn't work, the checksums are based the final bytes as read, clock s...

Re: CCITT CRC

Thanks Jon - always lovely to see something in BBC BASIC :D - that's much more translatable into Java than the C equivalents which I'd been perusing (I'd done one but wasn't convinced it was working). Are the clock bits fed in to the CRC register too?
